We do not know the source of Emily and Harriet's income, but we do know that they lived with their brother Theodore in the Strawberry Hill district of Norwalk, until his death in 1905. The sisters continued to live together and neither of them married. According to their obituaries, they were considered "well-to-do" and had no surviving relatives at the time of their own deaths, in 1915.
She and her sister Emily died on the same day, from pneumonia; Emily at 4:00 p.m and Harriet at 10:00 p.m.
