I am sure that the Israel who m'd Mary Smith in Adams Mass was the son of Israel and Amity. Unfortunately, when I went into the NEHGS data base to look for it, I could NOT locate this marriage. According to Bob Phillips post, Amity (the dau), Israel the son and Amaziah (son) all married in Adams Mass. Back in "the day" (before all these internet places) there was no way to look for them.
I just turned up new info on one of the sons of Levi Phillips of Springfield in Danby VT; of course he was also named Levi. However, his D/R says that he was the son of his brother Stephen and sister-in-law, not Levi and Mary (Bradway) Phillips.
