Hi, M. I tried to work on these profiles a bit in connection with my Blanton ancestors, but got frustrated and put it down for awhile. All the profiles really need a complete rewrite with all the uncertainties accounted for, but there are branches of the family who are very attached to the myths, so it's difficult. There are a few sources that build a rough outline of the family.
The Blanton Bible records the marriage of Vincent Hobbs, Sr., and Mary Shelby, and their daughter Rebecca's marriage to William Blanton.
Much later, Job Hobbs completed an interview for his pension application where he lists all his siblings, and gives his mother's name as Ruth Thomas.
From those two documents, we know Vincent had at least two wives, we know the names of his children, and we know at least any children born from Job's birth and later were Ruth's. There are also apparently land documents somewhere that name his wife "Hannah." I personally believe this is evidence that Vincent, Sr., had a third wife, but that was a controversial suggestion.
That's basically what we know from contemporaneous sources. Only two children, Rebecca and Job, are connected with certainty to a mother. The rest need more work.
