Looking for info on David Campbell, born c. 1819 in OH. Married Mary Conway in Lawrence County, OH. Their children were John (m. Serena Adaline Faulkner), Eliza J., Thomas (m. 1st Amanda Baldwin, 2nd Annie McGowan), Lafayette, David (m. Elizabeth Hardy), Calvin (m. Sallie Baldwin), William, and Mary Ann (m. 1st John Roach, 2nd William A. Waugh). Are these names familiar to anyone. David is my brick wall.
