My 3rd great-great-grandmother’s sister had a baby a few years before that same sister married her husband in the 1860s. Court records from the estate of the baby’s grandfather (the father of the sisters) make it clear that the grandparents raised the baby–not the baby’s father nor the baby’s mother and her subsequent husband. The child grew to adulthood and have children of her own.
One researcher decided to change the child’s date of birth, the couple’s date of marriage, and the baby’s last name in order to make it appear to be the husband’s child.
