I've seen a few postings about the French Creek church. This may offer some clues. in 1925, shortly before my great great great grandfather Ole died, he wrote a letter recalling his arriving in your area in 1859. I'll start out in the middle and leave the names in , in case you recognize any.

and then we came to our destination,La Crosse. It wasn't worth calling it La Crosse at that time; it was only some board sheds here and there, a ramshackle hotel and a store of two.
Then we walked for 16 miles to Lewis valley and there were many of us. Some went here and some went there. Then we started walking again. We couldn't travel between north and south lacrosse as they do now. so we had to go down past the bluffs to come around the swamps. We didn't stay together because some could walker faster than others. I wanted to walk a little faster, so I lost the family group I should have been in and worst of all I carried the food for them so it got to be a tough trip for the rest of them The group that I walked with had a friend that worked in Onalaska that they located and he gave them directions to a place where they could stay overnight. Those people used to take in newcomes who were in need of information. You maybe remember one by the name of Osten Skaalaas. The next morning we started walking again and I found my own family. They had come to Andreas Johanson. He was related to mother so we were quite welcome there. Also Uncle Andreas Homma was there working for the summer for twelve dollars a month. They lived on the place that Lars Valion bought there in Halfway Creek. We stayed there for five years, but there wasn't any land around there to homestead. and one year we were at Kalastuen in Lewis valley. We moved to Abrahams Coulee that fall in 1865 to what is now the Fred Hagen farm. Johannes Berge moved there at the same time. Abraham Madson (grandgfather of Julies and Minnie Mason of Galesville) and Andreas Anstensen were there a short time before. As far as I can remember they all came together and organized the congregation in French Creek. I believe there were a few who had started the congregation there. I remember there was a lay preacher named Frederickson. He lived in Tolv-Stads house like a hermit. He lived alone and never married. We knew him from Lewis Valley. He had the first service that I was to in America. When he gathered enough from the congregation so that he had a confirmation class from Lewis Valley and Halfway Crrek. After that, Prof Larson came as a permanent preacher. He was there only one year before he went to Decorah. I was confirmed by him. There were about 50 or 60 that got confirmed that day in the preachers house in Halfway creek. they just go it ready before the preacher came. there were confirmands both from tempealeau and la crosse counties.


Note: Ole Dahl was married in 1869 in the French Creek school close to where the church would later be, so I assumes the first congregation was organized during the civil war years and maybe in the early 70's the first church building went up?
I know the Dahl name is quite plentiful in the Trempeleau County area, any shirt tail relation of mine out there?
