I did the research for my sister-in-law. We don't have any positive proof but believe the L A Van married to M J Jefferson was her gg grandmother.(known as Dolly). All I do know is story goes that sometime prior to 1900 she left her husband and children saying she was going home. We assume that was MS. They never heard from her again. She already had her oldest child when she married W J Jefferson.
Story was that some years later her brother came looking for her. But she wasn't there. No one remembered his name.
I thought about checking catholic birth records around 1880 but never knew which county they may have been living in at that time.
What year did Laurie Ann die?
Sorry I couldn't help you more.
Please let me hear from you if you discover anything new.
