Reprinted message number 16375 from Genforums-Kansas re 1920 census for Wyatt Perkins:
I finally found Wyatt Perkins listed in the 1920 census of Precinct 1, Hemphill Co., TX on page 23A: Wyatte A. Perkins, 30, MO, father b in KY, mother in KS Dorothy E., 22, KY, father b in KY, mother in IN Dorothy A., 6, CO Hazel D., 4 yrs 3 mos, CO "Wyatte" Perkins was a foreman in a roundhouse (railroad).
Couldn't ever find him in the 1930 census at all! I hope this helps a little.
Thank you for your efforts to locate this family - Jonathan.
