Clue on George's parents would be found in different ways:
A)Birth Certificate/ or delayed birth certificate
B)Baptism Certificate
C)Book reference
D)Interview with descendents on George's siblings' side(line) if available
E)Death Certificate
F) Census(very rare show up record)
G)FamilySearch.com if available
H)Marriage Certificate
I) SSDI Record
You should be able to find him and include his wife. Why do people guess
that flood destroyed records? Is that proof? If not proof, why don't you
try different location nearby or right location for Marriage Certificate?
Have you tried it before? Those dates(1894 and 1925) are not that old. It
should be found easily.
I continue on searching..
