Michael John's name and the date of his arrival in NY could certainly fit into Matthew's son's history. Do you have any reference to Michael's Marriage date and/or the name of his father from that record? Was your John married in NY? do you know what children were born before the move to NY if any? I'll begin looking at what references I have. I know that John was refered to in Matthews will in the mid 1890's but I don't know where he was. A little digging may turn something up.
