Hi, I have a note that JAMES BLACKBURN M MARTHA WARD in 1844/45 in Gibson Co. TN-( became Obion Co. then Weakley) They were both born in NC Martha died there in 1893. James died with dau in ky in 1903. Children Andrew d. before 1904; Frank; Emma; Preston; James;Robert' Henry d before 1904; Katie. In the same county WILLIAM BLACKBURN M NANCY WARD in 1845. Since they both married Wards maybe there is a connection with your Jacob N. I also have Jacob Blackburn m Jean Rawlings in Pendleton Co KY, 1821. He is probably too old. Miriam B.
