Wilhelmina Maier (my grandmother) lived in Northfield Township, a few miles north of Ann Arbor, Michigan.
The Maier family was from Krehwinkel, Germany. Other towns mentioned in the early history were Oppelsbolm, Buchenbach, Birchenbach, and Lirken.
Her families genealogy was researched by Mary Maier Werle and a book was edited by Linda Kociba and printed in 1990.
I have a copy if you need a lookup.
Here's the pedigree for my grandmother Wilhelmina Katherine Maier
