Great question, who is A.D.D. Warren...from what I have found (I think) Delila is widowed by 1900 and the two children are not living in the household...Still wondering about that Emma Melson listed as niece in his household 1880.....about the other Melson family I had asked about.... 1880 Lincoln Co. Mary Melson 62 Henry B. son 23 Warren, Mary J. g-dau. 15 This Mary J Warren is probably the dau of Johnson Warren and Egaltine Freeman, Johnson died in the war and Egaltine remarried Peter Melson, is this Mary listed above his mother?, making Mary Warren the g-dau now..
