Nothing is known of Mintie's background. Her husband, Hart Cummings, is buried at Odd Fellow's Rest. She is supposedly a widow and in a relationship with Theodore Eaves which would explain why they would live in The Old Bacchus Place isolated from major towns.
Red Dead Redemption
Mintie can often be found in Armadillo, going about her daily business, but can occasionally be found in other towns in New Austin. However, she can also be found at The Old Bacchus Place, where she appears to live with Theodore Eaves. She is also at Ridgewood Farm, where she also seems to live, even sleeping here, along with 2 other women.
Her poster lists her as a mother, indicating that she has children.
Theodore makes mention that he is in a relationship with Mintie. Since Red Dead Redemption takes place in a time when it was illegal for people to date interracially in the United States , this may explain why they live in such a secluded spot hidden from civilization.
