After about 1750 my knowledge of the Allen line is very sketchy, bucause Mary Allen married John Chapman.
Thus, the latest Benjamin Allen born in these lines and recorded in my notes is in 1717.He was a son of Erasmus Allen, SR., the Uncle to Erasmus Withers Allen, my ancestor.
Of course, Erasmus Withers Allen moved to what was then Rowan County, NC about 1770.It's quite likely that some of his cousins and second cousins might have also moved there.After all, families moved in groups and we find Allens, Waggeners and Chapmans all together in NC.
Unfortunately, I don't have lineage for the children of Erasmus Allen, SR, so my knowledge of his line stops with his four sons, including Benjamin b. 1717 and three daughters.
