Hi, Peter J. Gammons was my 2nd great-grandfather. He was married 6 times. I show that he married Amy John about 1878. I have a lot of information on the Gammons line and would be glad to share it with you. I am a descendant of Peter J. Gammons and Elizabeth Gordon(wife #4). I don't have any info on your 2nd great-grandmother but I do have info on Peter back to mid 1600s.
