Two Husbands?

I've never seen anything saying Abigail had two husbands, but it seems clear the 2nd husband listed here (Unknown Profile), is actually a mixture of the first Col. John Youngs listed, and Unknown Profile (birthplace & parents fit the 2nd listed Unknown Profile), creating a man who never really existed. I can understand where confusion can set in during research, but it definitely needs to be resolved so Abigail only has one listed husband. This is also affecting the children, as some seem to be half siblings.
