Back to Texas- The 20's

Jess and Minnie and now four children were back in Texas by the early 20's. These two pictures show them with their children. Alvin is the baby and he was born in Big Springs on April 20, 1921. The backsides of each picture are also shown. Notice the spellings of the children's names are different. Do you think the handwriting is the same?
Last week I was talking by phone to my Aunt Opal, born in 1919. We were talking about Nettie, Grandpa's mother. She said Grandpa didn't "approve" of her. Shortly before Granny and Grandpa moved back to Texas, she "showed up" in Ardmore. Actually, she had been living there for a while but didn't realized her first son, Jess, lived there too. Once she discovered, she made her presence known to Jess. Opal said Jess had three houses he had built there in Ardmore by that time, one he lived in and two he rented. Opal said she knew that he had sold them as quickly as he could to go to Texas in order not to be around Nettie.
Another of my Uncles, Roland, told me in an email that he remembers hearing that Grandpa sold Maytag washers in Big Spring.
