The marriage records of Jackson County, MI show that Mary J. Siddons (Sedden?) of Spring Arbor, MI and Jefferson L. Holcomb of Summit, MI were married on December 25, 1864. At some point, they moved to Texas and her headstone in Young County, TX shows dob as May 24, 1856 and dod as July 25, 1928. Various census records show her place of birth as Wisconsin or Ohio. I was told that her father may have lived in Young County, TX and could have been I. W. Seddens.And there is a John W. Sedden in the 1920 census for Young County.Would really appreciate any information on Mary J., who was my paternal great-grandmother.
