It's possible that we have a connection. Coryell County is further south in Texas but my husband's grandparents moved to Caddo, OK and other places in OK. Gainesville, TX is 30 miles south of where we live in OK.
My husband's line is: Richard Dollins & Elizabeth ? Presley Dollins & Ruth Alexander Joel Dollins & Mary Armstrong Joel Thomas Dollins & Elizabeth Demaries Orrick. Hugh James Dollins & Emma Florence Powell Estelle Janette Dollins & A. A. Nichols
I noticed that several of the Dollins descendants have named their sons William Andrew "Bill" Dollins, which one is your Bill descended from?
