Sara: Pardon for the delay in replying; I have been off the net while my monitor was being replaced.
It is my belief PWK was an older brother of Samuel Kerlin, born 1800 in Georgia.Other siblings, I believe, were John, maybe Jacob, William, Margaret, James, and David--all older than PWK and Samuel.The Lowrimore Family Bible has Elizabeth (born 21 October 1762 in VA; death 24 Nov 1830 Elbert Co, GA) as the mother of Margaret (who married Andrew Lowrimore 22 Dec 1820 in Elbert Co, GA).
I have no clue as to the father (husband of Elizabeth); finding him has been my quest.
John Kerlin married Anna Lesley 26 Dec 1810 in Oglethorpe Co, GA; Anna was sister of Mary "Polly" Lesley who married my PWK 15 Dec 1820 in Oglethorpe Co, GA just a few day before Margaret Kerlin married Andrew Lowrimore in Elbert Co, GA (see above).
Of course, David and Samuel married Kinnebrew sisters Icy and Elmira.William married Mildred Brown; William's will was probated in Elbert Co, GA. The widow Mildred Kerlin later remarried.
I have very little data on Jacob and James.Indeed, they may not have been siblings; but probably close kin in some way.
I have been researching the Kerlins for over twenty years and have much to share.Please type back at me at email@example.com.
