I need some help, and am not sure where to turn.

Information I have says there was a Mennonite Church in Franciscoville, Jackson County, Michigan.

Looking for a way to contact that church, if it still exists, and see what records they might have for:
Paul Johannes Haering, his wife/widow and son, Johannes, born ~1881...
widow and son returned to Stuttgart, Wuerttemberg, Germany, after the minister passed on, reportedly & according to family folklore, in Jackson County.

I can not find any trace of this man, or his family in my records searches for census, Michigan GEN DEX...or emmigration records so far.

Please help us. Thank you.
Even a look up in the local phone book for a Mennonite Church in the area would be helpful.
