Your grandmother Dolly's maiden name is Wheeler. The Wheeler family is from northern Minnesota, in the Remer/Longville area. I know that's your Dolly as I know Dolly married a John Menominee and lived on a reservation at some point. Dolly was my grandfather Lewis' sister. They had a large family, see attached pic... I think she's one of the ladies in the front... I'll have to ask my aunt as she knows all about this side of the family. Your dad is one of the babies that the ladies are holding, as the babies are Ronny and Rudy. I never met my grandpa Lewis as he died from CJD in the 60s.. Our family has familial CJD mutation, which took my father, some of his cousins as well as my grandfather. The Wheelers are of German, Polish (Prussian) and English descent in addition to a few other things. Let me know if you want more info.
