Jefferson Lorenzo aka Lorenzo Holcomb is reported to have been a farmer in Dallas, TX. He was born Sept. 23, 1848 in Jackson County, Michigan, to Harrison F. Holcomb and his wife, Delia Ann. I'm seeking to document whether he is the father of my grandfather, James Robert "Bob" Holcomb of Young County, TX. Not having much luck, and could sure use some of that friendly Texas help.
