I don't have access to the 1930 census at home.Well, that would explain why I wasn't finding Lawson on the 1880 census.(^_^)
Looks like some of the family stayed in the same area.Combined info TX Dth Idx and SSDI:
Alexander, Gus R, b 17 May 1927, d 14 feb 1978 Falls Co, TX; last benefit Cameron, Milam Co, TX; SS card issued in TX.
But, I can't find a George or a Mitchell Harrison Alexander on the 1900 TX census that looks like a match.And, can't find Lawson on the 1920.The census index I use has to be an "exact" match or it will not call up the entry.
