Thank you Joan,appreciate advice. I noticed too I spelled the GRESHAM surname in my query wrong. I put GRESHMAN,when it should have been the GRESHAM/GRISHAM.I have also found out he had a relative living next door to him in 1920 census ROOSEVELT County, a Thomas P.?GRESHAM ( the letter was not plain) his wife was named Ada. Maybe this was a bro. of Mather?
