Your post is old, but maybe your sitll outh there. Annie Tappy was my great aunt. Her parents were William and Julia Bordeau. I have been trying to figure out this family unit for a long time. Have you gotten more information since your post?
My uncle Harris (who remembers visiting aunt Annie and William when he was young) said some thing about 2 of their sons starting a machine tooling business (or similar industry) in a old Ford building in Kingsford. Do you have information on that?
