Some wonderful person emailed me with the FHL #'s--I have them "safely" tucked away--when I find them, I'll let you know.
In case this person sees this again--please help!
There are 2 Trinity churches in Milwaukee. One was the mother church to St. John's (what we want) and the other is Evangelical Trinity (E&R later to be UCC). The Trinity Lutheran is the difficult one to find. St. John's records are in it.
I'll keep searching my "files".
