Ben, I don't know if you still will get replies, but I have direct connections to Mary Endicot/John Porter in my family tree. I think if you look online these days, you will find a wealth of information on them. Just google both names on the sme line, there will be numerous references. They were very prominent citizens of Salem, Massachusetts.
