Thank you for your help. My Dorcas was married only the one time, to ABC Dean, as Hunting for Bears confirms. That leaves out the 2nd Dorcas.
I have not been able to prove her parents, but I don't believe them to be Joel and Ruth. It is my understanding that she had only one sister, who may have been named Frances. Dorcas was disowned, as family legend has it, by her father for either marrying my 2nd great-grandfather, or for helping Frances marry the "wrong" fellow. I want to find out if her father was in fact Albert and who her mother was, and is the story true. It goes on to state that they were sent off to live with her uncle, believed to be her mother's brother. Barksdale may have been the last name. My searches have turned up only one unmarried Barksdale, Martha, who seems to have died "unmarried".
So, I am stumped.
