I believe the John McConkey you are talking about is my 4th great grandfather. If you look through some of the postings lower on the forum page, you should find some references to five brothers that came to the states from N. Ireland in the mid 1700's. William, Alexander, John, James and Hugh. I believe John is the son of the same William McConkey who was the owner of McConkey's Ferry. Unless it is a different John, he would have been born there in Lancaster Co., PA. I have a record of marriage of John McConkey & Leah Hartzell Owen in Ohio in 1812. I'm just getting started back in my research after a couple of years, so when I get things organized I'll see about getting some info to you. Do you think we could be speaking of the same individual?
