My Abernathy family lineage comes through Robert Aberne[a]thy born 1635, who came to America in the 1600's on the ship Kemp.He is recorded as being married to Sarah Cubisha [spelling]. Sarah's parents [John and Jane Bell] are also on this list. Christopher Tilghman, father of Christine who married Robert and Sarah's son, Robert is listed as well. [Our Family's Known Immigrants--Internet source]. Is this the same Robert you have listed as an indentured servant who could not write? It seems odd to me, that Robert A. Abernethy and wife Sarah Coppesha would be among the unlearned.My family includes Summerville [Sommerville], Devonshire and Mile's families as well as Abernethy's. Are these all common families of Scotland?If so, then was there a Lord Sommerville, and if not, then why would nobility marry among commoners?
