I did somewhat. Merin, anyhow. But no Evangelical records. Somewhere I read that Czech Hussites became Presbyterians here, and that is what the Trutnas were first in the US. Later, their church either merged with a Congregationalist church, or the Trutnas changed to Congregationalist. I also looked for Protestant entries in the Catholic books, didn't find any in the few pages I searched (computer was slow that day).
About a year ago my husband and I stopped to look at the Presbyterian Church which they attended. Very pretty. Quite different in style from RC churches. My next project would be to find out where those records are stored (the Presbyterian church here.)
