I am searching for information on William McCadden born April 26,1829 possibly in Belfast, Ireland. He served in the Mexican War in a NY regiment. He settled in Santa Fe & served also in the Civil War. he was married twice to: Margaret Hoolihan (who died in Santa Fe), and to Martha Brooks (who died in Minnesota). He had 3 children by his first wife: William Thomas McCadden (who settled in Oklahoma City), Margarete (Sr. Coina who died in Cincinnati), and Elizabeth (married name Regnier). Children from his second wife are: Annie, Mary, Francis, Amy, Bessie, Charlie, Lillian, Josephine, and Mattie. If you have any information on this line of the McCadden family, please respond. Thank you.
