Joseph Robinson married Gladys B. Kent on Dec. 14, 1926. She died in 1932, and he married Flossie in 1935. It said Josephs parents were William Robinson and Fannie Goodchild.
This was from the Michigan County marriages at www.familysearch.org
I didn't find a marriage for Vera, but it appears the index goes to 1935, and the actual marriages to 1953, and I didn't search all of them, you have to browse.
