both worked at the Methodist mission in Kaposia — William as a carpenter and Martha as a teacher. Martha Brown reported that Helen spoke French when she came to live with them, suggesting that she learned the language from her Mdewakanton family and relatives. Sibley provided for his daughter financially, paying the Browns to support Helen, and financed her education, including boarding school in the eastern U.S. As a young woman living in St. Paul, she was said to be fully acculturated and accepted by white society, with a considerable income as a result of Sibley's investment of her treaty annuities. Henry Sibley maintained a congenial and public relationship with Helen, although this reportedly upset his wife Sarah Jane; Henry's past relationship with Helen's mother fueled criticism in Republican newspapers, which questioned his character and called him a "Moccasin Democrat." Henry and Helen were often seen chatting at his picket-fence gate. On September 1, 1858, they were both very prominent in a St. Paul parade celebrating the laying of the transatlantic cable in September 1858, where Helen was one of 33 young women selected to represent the states of the Union. The Daily Minnesotian identified Miss Delaware as "Helen Sibley" with no further comment. In 1859, Helen married Sylvester Sawyer, an Anglo-American doctor, and was given away by Governor Sibley at her wedding in the front parlor of the Browns' house in St. Paul. They agreed that Helen would not use Sibley as her surname on the couple's marriage certificate, but Henry signed the certificate "H.H. Sibley" as a witness. Tragically, Helen died less than a year later of scarlet fever after giving birth to a baby girl who also died. In 1860, Sawyer wrote that Governor Sibley mourned the loss of his first-born child Helen "sincerely and truly." Other children Henry and Sarah Jane Sibley had at least nine children, four of whom survived until adulthood, including Augusta Ann, born in 1844; Sarah Jane, born in 1851; Charles Frederic, born in 1860; and Alfred Brush, born in 1866. Five died as young children: Henry Hastings (1846), Henry Hastings (1847–51), Franklin Steele (1853–63), Mary Steele (1855–63), and Alexander Hastings (1864). In 1868, their eldest daughter Augusta married Captain Douglas Pope, Sibley's former aide-de-camp who had been based at Fort Snelling. When his wife Sarah died in 1869, Henry was left with two young sons, including Freddie who was eight years
