Quakers were only permitted to marry other Quakers, and those who 'married out' (to marry someone not a Friend)were always 'disowned' by their meeting.This term meant that they were no longer Quakers. Quakerism started in England, and the commonwealth of Pa was established in 1682, by Wm Penn, as a Quaker colony.... the majority of the early Quakers who came to the New World, were English, and many from Ireland, although they were not Irishmen, but English who had moved there to escape English persecution.There were also many Welsh Quakers early on. The major work that contains much Quaker data is Hinshaw's Quaker Encyclopedia, and while it contains much data, it has nothing of the midwestern states.HInshaw is always a good place to start, but Earlham College, in Richmond Indiana is a large repository of midwestern Quaker info, so you might visit their online site to see what is available online. As you feel your family may have been Quakers, I'd suggest you just surf the net and read whatever you can find on the religion...without some sort of a basic understanding of the faith and it's workings,you'll flounder around and not have much chance of finding what you seek. There were Quakers in Ohio, starting in 1808....however, Hinshaw lists no meetings in Tuscarawas or Coshocton Cos.In fact, the names Isaac Finneyand Rachel Orr Finney did not appear in any of the records contained in Hinshaw. As to what other religions were present in the counties you mention, for that you need to do some homework, to determine what was there in the timeframe you're interested in.....I think I can promise you that there were Lutherans, Presbyterians, German Reform, Methodists, Batpists, Mennonites, and RCs.
