I would write your question to the
Lapeer County Genealogical Society
P O box 353
Lapeer, Michigan 48446
They are just opening up the new Lapeer Historical Museum and the Genealogy Group will have one room devoted to the research of Lapeer people.
It's right on Nepessing Street - 2 blocks west of the Court House.
I am a member and will keep your inquiry to make sure it gets answered
