Kerlin/ Carothers
The 1860 census of Steubenville, Ohio, lists another Kerlin family : William, 58, born in VA, Cassaline, 58, born in VA and Edgar B., 10, born in VA.
Today as I was rooting around on line, I stumbled upon this : A Cassoline Brown who marries one William Kerlin. Going back in her family, what did I find ? She had a sister named Hannah who married a certain Samuel Cruthers.
Winchester, Frederick Co, VA. Next place to look.
