The Wild family was from Oberachen and Leinfelden, Germany.
Caroline Christine Wild came to Ann Arbor, Michigan in 1889, in 1895 she married David Frederick Maier. They were my great-grandparents.
Her families genealogy was researched by Mary Maier Werle (her daughter) and a book was edited by Linda Kociba and printed in 1987.
I have a copy if you need a lookup.
