Did you have success finding records for this church? I am hoping to find a church marriage record for my GG grandparents who were married in St. John's in 1878 (and I'm assuming it's this church).
Also, I don't know if you've done other Milwaukee church research, but I'm trying to find information on a Immanuel/Emmanuel lutheran congregation that was pastored by a Kuechle/Knechle. My gg grandfather's family attended there c. 1873.
Thanks a lot,
