You did not give any date
The latest census available is the 1940

But what I could find is:
Texas Birth index 1903-1997
John Wayne Horton
Jul 1962 Winkler Co [where Kermit is]
F: Harry Thau Quattlebaum
M: Stella Mae Tidwell

Could not locate their marriage -
You would have to now their birth dates to verify if they have died or not
Assuming you are trying to locate siblings or cousins of his in order to verify other family information

Good luck
