I'm trying to find immigration for Michael McMahon, his wife Honora Reardon, or any of their children. There son John McMahon was born in 1830 in Ballyduneen - Kilmihil Parish. The first information I have on the son John in the USA is that he is married to Mary Gorman and in 1850 they are in Pennsylvania with three children, all of whom were born in PA. I can only assume that he immigrated sometime in the early 1840's? I have all the information from that point on, if anyone is interested. But anything anyone could tell me about before he entered the USA would be appreciated. Brothers? Sisters? Immigrated into? Immigration Date? Did any of them travel together? Thanks so much!
