Maria was listed in the 1880 census living in Centralia, Wood Co. (ED 232 SD 4 pg 495A), age 54. She is listed as divorced. Her mother (listed as as Maria's boarder in the 1880 census) died in 1882 "at the residence of her daughter Mrs. Andrew Bean", according to her obituary. I am unsure if this is refering to Maria's sister, Ellen, or if Maria remarried again.
Maria's sister Eliza was my great-great grandmother. I would be interested in any information that you may find. Thanks!
