Minnesota History Taught Through the Lives of Hypolite & Angelique Renville Dupuis.

Minnesota History Taught Through the Lives of Hypolite & Angelique Dupuis 

by Daniel C. Munson 

The Hypolite and Angelique Dupuis House on the  

Sibley Historic Site is a handsome structure. Built of  

bricks shipped to Mendota from Milwaukee in 1854, it  

has every bit the “curb appeal” of the larger Sibley and  

Faribault houses on the same site. The handsome red 

brick, the symmetrical placing of the stately vertical  

windows with the simple yet pronounced cornice  

practically shouts “mid-19th century respectability.”  

The house fell into disuse in the early 20th century,  

but it was restored in the 1920s by a local chapter of  

the Daughters of the American Revolution and has  

been used many times since for receptions, teas, and  


While it may be an impressive and interesting  

structure to students of Minnesota architectural  

history, the lives of its original owners are at least as  

interesting as the building itself. The lives of Hypolite  

and Angelique Dupuis—each of them individually and the two of them together—are  fascinating and meaningful. Taken together, their stories nicely illustrate a good deal  of early Minnesota history.  

Let us then consider more fully the lives of Hypolite and Angelique Dupuis.  Angelique was born Angelique Renville around 1815, the child of Joseph Renville,  Jr. and a Mdewakanton Dakota woman now known to history as Mary Renville. Not  much would normally be known of Angelique’s early years, but her father was a  prominent figure across the lands that would become the state of Minnesota, and it  is through her father’s well documented life that a picture of Angelique’s early years  comes into some focus.  

Joseph Renville, Jr., Angelique’s well-known father, is thought to have been born  around 1779 at Kaposia near present-day St. Paul. Historians tell us “His father was a  French trader of much reputation. His mother was a Dakota, connected with some of  the principal men of the Kaposia band.”1 Joseph, Jr. is said to have been sent away as a  youth to Canada to receive schooling and religious instruction from a Catholic–by one  account a Jesuit–priest.2 We do know that when the U.S. government sent Lieutenant  Zebulon Pike north on the Mississippi in 1805 it was Joseph, Jr.—a man conversant  in English, French, and Dakota and knowledgeable of the area around Mendota–who  acted as interpreter at Pike’s conference with the Dakota people. Pike later wrote that  Joseph was “a man respected by the Indians, and I believe an honest one.”3 Joseph,  like many other Indian leaders, later fought with the British in the War of 1812, leading  Indian troops in battles with American forces at Prairie du Chien and Fort Meigs in  northwestern Ohio. Joseph lost his British army pension when he became an American  citizen in 1823, and shortly after he set up a fur trading lodge at Lac qui Parle (“Talking  Lake”) along the Minnesota River near modern-day Montevideo.

Joseph’s wife Mary was also a member of one of the leading Mdewakanton families  — Little Crow was a first cousin — just like Joseph’s mother. The Mdewakanton were  a “woodland” tribe of the larger Dakota people, a tribe that spent most of its time far  downstream of Lac qui Parle in the more wooded area that is now part of the vast Twin  Cities metropolis. Mary was therefore not a member of the Dakota tribes nearest Lac  qui Parle, the Sisseton and Wahpeton tribes. Angelique, daughter of Joseph and Mary  Renville, was therefore three-fourths Dakota–specifically Mdewakanton Dakota– 


A Presbyterian named Thomas Williamson arrived at Fort Snelling in the early  1830s looking for a place to begin a mission, and Joseph Renville invited the Reverend  Williamson to place his mission at Lac qui Parle.4 The mission began a school to  instruct young people in English and in Christianity, the first such school in Minnesota.  Angelique, the daughter of a man who valued formal schooling and the leader of the  Lac qui Parle trading post, attended the school that was started at Lac qui Parle in July  1835.5 The teacher was Miss Sarah Poage, the future wife of missionary Gideon Pond.  Thomas Williamson later wrote that these young students like Angelique “learned  to read English.” Reverend Williamson may have underestimated the difficulty of  learning a written and spoken language so different from their native Dakota tongue,  going on to comment that “I never heard any of them speaking it much.”6  

Working at that same trading post was a young man born far from Lac qui Parle, in  French Canada, an energetic and gregarious fellow named Hypolite Dupuis. Baptismal  records tell us that Hypolite was born on October 16, 1804 at LaPrairie de la Madeleine,  a village on the south side of the St. Lawrence River near Montreal, Quebec, the son of  Michael Dupuis and Marie Louise Denault. Little is known of his early life, but he may  have had family connections with the fur trade, because there were a couple of other  men named Dupuis on the rolls of the American Fur Company, including Hypolite’s  brother Michael who would also find his way to Minnesota. 

We know that by 1831 Hypolite Dupuis was working for Joseph Renville at Lac  qui Parle, a thousand miles west of La Prairie de la Madeline. Young Hypolite Dupuis  must have been given a solid education in that little village near Montreal, because he  was employed at that trading post as a bookkeeper. 

Bookkeeping in the 18th and 19th century was a different and, in some ways, more  complicated business than it is today, when computer programs and the stability and  wide acceptance of the U.S. dollar has made it a systematic and somewhat routine  matter. 18th and 19th century bookkeepers had to wrestle with goods of indefinite  

value that often could be sold at different prices in different locations (involving  different and non-negligible transportation costs) as well as a mish mash of different  currencies—gold, silver, bank notes of varying soundness, etc.—that riddled the whole  process with complexity. 

The upshot of all this complexity and uncertainty is that when business owners found  someone who could make sense of it all they would endeavor to keep them around.  Joseph Renville must have spotted this bookkeeping skill in the young Frenchman— arithmetic is an international language—and it appears young Hypolite caught on and  became known for it among others connected with the larger trading company. 

Hypolite’s talents extended beyond bookkeeping. He grew up speaking French,  which worked fine among the traders along the Minnesota River–many of them spoke  French–but he quickly picked up both the Dakota and the English languages spoken  along that trading route. This blend of languages often formed itself into a distinctive  “patois” that most of the residents of the area could use to converse, and young Dupuis  quickly became a master of this odd dialect.  

Such a young man might have had considerable appeal to the Dakota women who  lived nearby. Hypolite and his fellow traders and voyageurs were a popular group.  They plied their fur trapping and trading skills along Minnesota’s rivers and at trading  posts at Lac qui Parle and Traverse des Sioux and Mendota and Prairie du Chien with  a fun-loving, “devil-may-care” attitude. Even missionaries, religious people normally  somewhat cold to a pursuit as “worldly” as fur trading, could not help but enjoy them.  Samuel Pond ran a mission to the Dakota along with his brother Gideon for many  decades, and he reminisced in print of those “Good Old Days” of the 1830s and `40s  when those traders and “their jolly, reckless voyageurs…passed up and down those  rivers.” Pond reflected on the fact that although progress had replaced them, “there  are a few of us yet left who…sometimes almost wish that, instead of the shrill scream  of the steam whistle, we could hear again the merry song of the boatman, and see, just  once more, our old friends the traders, each one at his post.”7 

Angelique Renville married young trader and voyageur and bookkeeper Hypolite  Dupuis. They were married by the Reverend Thomas Williamson at Lac qui Parle in a  ceremony described by missionary Stephen Riggs in his daybook: 

“Quite unexpectedly, this afternoon [January 11, 1839] we received  an invitation to a wedding at the Renville’s, one of his daughters  marrying a Frenchman…Mr. Renville, who is in part Dakota, received  us with French politeness, and soon after the rest of the family entered.  These, with several Dakota men and women seated in benches or on  the floor around the room, formed not an uninteresting group. The  marriage ceremony was in French and Dakota, and was soon over.  Then the bridegroom rose, shook hands with his wife’s relations, and  kissed her mother, and she also kissed all her father’s family. 

“When supper was announced as ready, we repaired to a table  amply supplied with beef and mutton, potatoes, bread and tea.”8 

Despite the formality, the marriage was not a Catholic ceremony. Hypolite was a  life-long Catholic and so may have found it a little wanting. Shortly after Hypolite was  hired by Henry Sibley to work at Mendota, Hypolite and Angelique were married again  in a Catholic ceremony at the St. Francis Mission at Mendota in 1842.  

Hypolite Dupuis became a trusted advisor to Henry Sibley at the Mendota office  of the American Fur Company, the center of the fur trading business in Minnesota.  Sibley was an English-speaker first and a French-speaker second, Dupuis the reverse,  but they conversed well enough that Hypolite became Sibley’s private secretary. It is  widely believed that Hypolite managed the fur business for Sibley when Sibley was

away from Mendota. 

Hypolite Dupuis was therefore an important–and popular–figure  at Mendota. In “Pioneer Chronicles,” Hypolite is described as “a  great character” who “could talk like a streak of greased lightning  in a mixed language of patois, Sioux and English which only those  familiar with Northwestern inhabitants of that day could comprehend.  When things went wrong, the villagers all knew it by the excited  Frenchman’s vociferous clamor of mixed tongues, ferocious gestures  and blazing eyes, and it was always better than a circus to them.  Hypolite was as good hearted, generous and companionable a fellow  as one need wish to meet, when he was in good humor, which was his  normal condition.”9 A newspaperman interviewed Hypolite in 1868  and wrote that he was “as full of anecdote as ever” and that “an hour  or two whiled away in his company is no loss.”10 

Sibley’s absences grew longer and more frequent when Minnesota  was organized as a territory in early 1849. Sibley was the territory’s  representative in the U.S. Congress, and he spent a good deal of time  in Washington, DC lobbying on behalf of its residents. Territorial  

status triggered the demand for a treaty between the U.S. government and the Indians  of Minnesota, and Hypolite’s boss was right in the middle of the action. Sibley was  a champion of the interests of his many Dakota constituents, and Sibley’s letters and  speeches show how influential he was in making the terms as generous as possible for  the Dakota.11 Two treaties were concluded in 1851. The Mdewakanton and Wakepute  tribes near what is now the metro area concluded one—the Treaty of Mendota–and  another treaty was made with the Sisseton and Wahpeton tribes further west—the  Treaty of Traverse des Sioux. 

A critical part of those agreements and one that was not technically part of the  treaties themselves was the extinguishing of debts that Dakota hunters had rung up  in the 1820s, `30s, and `40s. This was done using a document known now as the  “traders’ paper.” Hypolite would have been instrumental in toting up these debts on  behalf of Henry Sibley and his firm. It is interesting to observe that Sibley’s claims  presented in both these “traders’ paper” documents were meticulously kept, with total  debts quantified to the penny.12 (Many of the other traders claimed debts in round  numbers like “one thousand dollars” or “four thousand dollars.”)  

Angelique’s involvement in these treaties is also interesting. The Dakota Indians  were given money in the form of yearly annuity payments in return for agreeing to  relocate to a reservation alongside the Minnesota River–but what of those Dakota  like Angelique who were not going to relocate but who were nonetheless considered  members of the tribes? The solution arrived at was to give such “half-breeds” a share  of the treaty proceeds in the form of single, up-front cash payments to each. Angelique  had five children at the time, and her status meant she was given $1500 (i.e., five  children at $300 per child) out of the proceeds of the Treaty of Traverse des Sioux. It  is interesting to observe that Hypolite signed the treaty even though he was not listed  as a trader and was not claiming debts himself, perhaps because he was signing on  Angelique’s behalf or vouching for the debts claimed by Sibley. The $1500 figure is  not a great amount of money today, but it was then: it was enough to pay for nearly half  the cost of the red-brick Dupuis House built a few years later. 

Angelique’s status as a “half-breed” is memorialized in that Treaty document, but  the specifics of her life story are more interesting than that simple ethnic label. Born a  member of one of the leading Mdewakanton families, Angelique is a transitional figure  in Minnesota history. Dakota by birth and kinship, her youth is spent on a fur trading  

post and she is taught to read and write by missionaries, and by the 1840s and `50s she  is raising baptized children as the wife of a bookkeeper.  

The wilderness that was such a critical part of Hypolite’s fur trading business was  quickly vanishing during Minnesota’s hectic population boom of the 1850s. The white  population grew by leaps and bounds, doubling every 18 months or so for a half-dozen  years. The fur trading business was doomed by this growth, and shrewd traders like  Dupuis and Sibley knew it. They wound up their trading business in 1853.  

That same year, the Mdewakanton tribe relocated from near St. Paul to its new  reservation land some 100 miles upstream along the Minnesota River.  Consider Angelique Dupuis, living at Mendota that September of 1853, mother  now of six children and one Metis orphan, and ponder her thoughts as she watched  her kinfolk, those hundreds of Mdewakanton, travel past her house as they made their  way up the Minnesota River to try to practice their ancient way of life on their new  reservation lands just downstream from Lac qui Parle. Angelique must have felt the  force of that transformation of the lands of Minnesota as few others could. Hypolite was now out of the fur trading business, but the commercial world still  beckoned. He envisioned running a general store to serve the growing local population,  a store right on the grounds of the old trading company at Mendota. He decided to  do the thing up right. He constructed that handsome personal residence that we see  today alongside Highway 13, and he partnered with a man called G.S. Whitman to run  a general store on ground level.  

Hypolite and Angelique and their large family lived in quarters above and all  around that general store. They had a seventh child (“Henry Sibley”) shortly after the  brick house was finished, and five years later an eighth (“Hypolite Paschal,” or “Paul”).  

Hypolite’s general store would not survive the deep economic recession that  followed the nationwide Panic of 1857. It was a financial swoon that started out east,  but it wreaked real havoc on the new and vulnerable and credit-starved Minnesota  economy. Undaunted, Hypolite continued to serve at various times as Mendota  postmaster, Justice of the Peace, and Dakota County’s first treasurer. All this evidently  did not keep an energetic man like Hypolite Dupuis quite busy enough: he sold his  handsome Mendota brick house and moved to the Devil’s Lake Reservation in North  Dakota to work as storekeeper at the Fort Totten Indian Agency. 

Hypolite was roughly 65 years of age when he moved to the Fort Totten Agency,  and he may have discovered that he was not as quick and spry and energetic as he once  had been. We don’t know precisely when he returned to Minnesota, but we know that  he was back in Mendota in July 1879 when he finally lay down and departed this life. 

Angelique lived another ten years, joining Hypolite in that “undiscovered country”  on the second day of 1890. She was survived by many children and grandchildren.  Hypolite and Angelique’s many descendants today live and work and brighten the lives  of their friends and acquaintances here in Minnesota and throughout the rest of the  country. 

One of those descendants is Mary Corinne “Connie” Willwerscheid, nee Rafter, of  Eagan. She is the great granddaughter of Marie Agnes Dupuis, the third child born to  Angelique and Hypolite.13 She was born in 1934, and while growing up she wasn’t  told much about her mother’s ancestry. She remembers quite clearly Minnesota’s  celebration of 100 years of statehood in 1958, and the muffled tones her mother used  when the occasion caused the subject of her ancestry to be mentioned. It made Connie  curious, and when she researched and discovered her mother’s family’s “mixed blood”  ancestry she was told by one of her siblings that she was just “telling one of her  fairy tales.” Now these many years later those siblings acknowledge their family’s  fascinating story. Family members reached out to the helpful people at the Sibley

Historic Site and learned more about those interesting ancestors of theirs.  Connie raised her five children in a handsome modern house built very near where  the Treaty of Mendota was signed and just a couple of miles from the Dupuis House.  She sent her children off to Henry Sibley High School, and those grown children live  still in Minnesota (when they are not vacationing in various exotic locales). When an  interested writer/historian asked if they would all gather for a photograph, they (along  with a few spouses) quickly agreed on a time and rallied around their mom to take the  photo presented here.  

Those who pay a visit to the Sibley Historic Site today usually walk through the  Sibley House and listen to the dramatic details of the life of the state’s first governor  and congressman. A stroll back up the hill to the left takes the visitor to the house of  Hypolite and Angelique Dupuis–that handsome red-brick structure that serves now as  the Visitors Center. Such a walk, when accompanied by a little reflection upon the lives  of the original owners, repays the effort. Hypolite and Angelique started life in vastly  different places and circumstances, but their lives came together in Minnesota and put  them at the center of much early Minnesota history. To give a few moments’ thought  to the arc of their family story is a worthwhile exercise.
