Thomas Adams - Parents - Needs Review

My family tree sprouts from Ulster Ireland. I have put the parents as John Adams and Elizabeth Hughlings, both born in Antrim, Ulster Ireland. There is very conflicting information about the birth of Elizabeth Hughlings. There appear to be two Elizabeth Hughlings Johns with the same parents. The birth dates are the same but the death dates are different. One was born in England, one was born in Ireland. That being said John Francis's parent are different (in my tree) than the ones you have posted. It is certainly a mystery. I have been using a geneology paper I found on line that supports my tree, so that's what I have been using.
