Judy, Peco may just be an abbreviation for Pendleton Co. I never thought of that. It was on a tombstone in Illinois as a reference to where the husband died. He died in 1827 and according to the 1830 Pendleton Co. census, the family was living in Franklin. You mentioned Rick Toothman's book on Pendleton Co probate records. Do you have the name of the book and where I might find it? Thanks for all your help. Betty
