Fanny Allen was the daughter and eldest child of American Revolutionary War leader, Ethan Allen, and his second wife Frances Buchanan Allen. She was the first woman of New England birth to become a Roman Catholic nun.
In 1807, upon asking for permission, Fanny went to Montreal to study French, where she converted to Catholicism. Fanny became a sister in the Religious Hospitaliers of St. Joseph and spent the rest of her life nursing the sick and indigent. She was, however, noted to be the official hospital chemist.
Like other members of her family, she died of consumption on September 10, 1819 at the Hotel-Dieu. She was 34.
The Fanny Allen Hospital in Colchester, Vermont, run by her order, the Religious Hospitaliers of St. Joseph, was named in her honor.
