So, to start, I think it's a bit early to say that John may forever remain a mystery. These sorts of mysteries often take some time to work out, possibly even years, depending on the accessibility of records. The Reverend James of Moy was the son of the Reverend James of Kilmore in Armagh. While most records of these people have been destroyed, enough remain to confidently create the brief sketch that I have already provided. There's no doubt about any of that. The Rev. James of Aughmacart does not appear to be closely related to the Moy Dobbins family - purely coincidental there. The problem, obviously, is making that connection with John of Moy/Whitehaven, understanding that there is still a possibility that John of Moy was not actually the son of Rev. James of Moy. I do believe this could be solved with a deeper study of the individuals in Ireland and England to see if/where their stories come together, or if some evidence comes up to exclude the connection to Rev. James.
