Well, no more confused than I've been before now, I guess! Do you have any kind of documentation of these relationships or just the same thing I have: family stories. I'd sure love to find a bible page or a will or a baptism record or marriage record from some semi-official source like a church or town record.
Of course, this is a lot to ask at this period of history and especially from people as pressed as these ancestors of ours seem to have been.
Does your family have the Mennonite/Amish/Anabaptist history in your records too? Has one of the men of your family done the DNA testing?
