There could be a connection and I just haven't found it yet. I noticed quite a few Marguerite's in your info and as it turns out, my mother in law is Margaret (they asked that she be named Marguerite and the Nurse got to wrong on the birth certificate.) I realize this is only a small clue, but I'll search through any records I can find for that Sauve you said was the only one who'd gone to N.A. and see if I can find any evidence through that name. Please be on the lookout for a Sauve/Sitterding connection around 1920's Bay City, MI(mother in law was born in 1925).
