Such beautiful photos - it is a shame that no one seems to know who these charming people are!The only river I've ever seen in Texas is the Red River on the border between Texas and Oklahoma - it looks much like it does in the photo - but that is hardly conclusive!
I was thinking it might be the Red River. I wonder if we'll ever find out?
Edna Vitz had a daughter named Robin... I wonder?
I think perhaps this is Robin with her girl born c. 1944 (she also had a son born around 1953).Robin was born in 1925, so she would be 25-30ish by the time of these photos.
