I wish I could tell you I do have more information on this Joseph, but I don’t.I did research further since the McMahans have been known to go by the McMahon spelling as well.And, yes, I realized there were more Josephs.Some moved to Chicago and others to Ohio.Reason for posting this Joseph on this forum hoping it would help those who are searching for him.
I ran into the same problem with a certain John McMahan. There are a lot of out there!I cannot tell you how difficult that was, but I finally found the correct one.
Good luck! If someone claims this Joseph McMahon, I would love know.
