That makes it difficult. "My" Euwers were Covenanters, or Reformed Presbyterians. If you can find any records of those congregations where your couple was a member, that might be helpful. Check for their marriage record, and sponsors for christenings or baptisms for any children they had. Check also any will or probate records if her husband died first. You may have to go to Pittsburgh to do that. I'm still very interested in anything you find on this lady.
