Wilcox-Gay Recordio Discs (1948-1949)

I found these records at the Goodwill in Hopkins, MN, on July 26, 2015. They contain recordings of an unknown family, with most of the recordings done by a girl named Sherry (November 15, 1942-?). Her (presumably) sister, Judy, is also in some of the recordings as well as their mother, father, aunt Delores, and other extended family members. If anyone knows which family these recordings are of, please let me know and I will try to get in touch with them!
