I have a distant cousin in the Poitevint line through Linnie Bell and she has more information of Mary:
Name: Mary Holly
Birth: 1794
Married: Alexander Wilson and Daniel Alderman
13 children
I have never offered more information to someone so not sure how this works, I was just trying to fix some inconsistency issues in my tree. The information to back up her birthday was found on a 1850 Federal Census, Mary Poitevint, daughter of Isaac Poitevint and Elizabeth Treadwell, is found on 1850 census as "Holly Alderman," age 56, thus, making her year of birth 1794.
