The notes of my paternal grandmother, Lucille Alena [Mattson] Robinson, show Mike Shelson as a twin. However the notes don't say to which of his siblings he was a twin with. Michael Shelson was one of eight known children born to, Norman Shelson & his wife, Marian L. [Mattson] Shelson. Now, you know, excatly what I do about this young Mattson.
