There is a Dreisbach Church (note the "R") in Buffalo Valley in Union County, PA. Union Co. was created from Northumberland in 1772, and there are lots of PA Dutch in the valley. It is very rural. I cannot say how far the church goes back, but I know I have found burials in the churchyard as early as 1815. The Dreisbach is, today, a United Church of Christ; before 1957, I believe, it was German Reformed. Hope this is of help!
