Polly had only one brother, David Fletcher. However, he never married so the possibility of his DNA is remote, to say the least! Still, his name my provide genealogical clues. View 1850 LA-Rapides-Not Stated-Images 45 & 46 for William Rollins age 36. I'll go out on a limb and offer: 1) the two youngest sons were inspirations for naming your great uncle and 2) their older brother, William age 14, eventually wed Sarah E. Baker. "Eventually" used because he married Lucinda Jane Robinson, first. They had William Smith Rollins ca. 1858 and, hopefully, his descendants will be sources of DNA? Confused? Probably justified 'cause it seems I'm on a journey from Delaware to Sandusky, OH via Oakland, CA! Totally relying on "litmus tests" developed during 20+ years of research.
