You say you want info on Welchs and give names of your grandparents -- are they still alive?By entering their names in TX Birth Idx Online 1926-1949 I found the following children:
Welch, inf of O.E. b 11-6-28 in childress Co. Welch, inf of O.E. b 7-12-29 in Hale Co. Welch, Glen Marion b 7-2-1930 in Castro Co. Welch, Barney Ray b 11-13-1933 in Cottle Co.
Mother's name entered as Lora Ray, except one entry was Lara.Father entered as O.E. Welch, except one entry was Obie.Usually entry listed as "inf of" means child was still born, or died at birth.Note how close 1st & 2nd entries are, looks like 2nd birth wasn't even full term.
If your grandparents are deceased, do you have copies of their death certificates?They would show names and birth locations of their parents.
