Thank you. No, I haven't been to the YCHT. I don't travel to do research anymore. If you can find anything I would be grateful.
I know that the Daniel and Lewis Miller I mentioned were not originally from York Co. They emigrated from Allendorf/Lumda, Hessen in 1861 and were in N. Codorus Twp by 1870 with their mother Catharine. Sometime after that the men and their wives moved to Baltimore, MD. I'm not sure if their mother died in York Co or if she also moved to Baltimore.
If you find a trace of the marriages I'll appreciate it. If not, that's the way some of these searches end, isn't it?
