The Twin Falls area directories haven't been much help yet. There is a C.M. Terry living at RR3 in Buhl, through 1960 (but not 1962). I can't confirm that this is Columbus M., but that is the most likely. I see only one other marriage in the Western States Index, for one daughter.
Groom Last Name: SMITH
Groom First Name: Earl A.
Bride Last Name: TERRY
Bride First Name: Lora F.

I have not had much time to check for the children.
There appears to be a matching Lora F. Smith in the SS index, who was born, 20 Nov 1913, and died 12 Nov 2006, last residence Pocatello ID.
