Looking on info on Owen Murta. First mention of him was in Pendleton Co. when he got his citizenship. Next was his marriage to Harriet (Isobel) McKinney in Scioto Co., OH. In 1880 he was possible listed as Owen Marta staying with a family named Mauts in Pendleton Co. as a boarder while his wife and son lived with her father, Darius McKinney. After that he disappears. Harriet remarried in 1881.
Hopefully, someone out may have some info on this man from Ireland.
