I don't know how we have missed our mutual searches for John Adams (1765-1838). I have lots of info on this line. I am looking for origins of his father, John, Sr., who's will I have tracked down at the Westmoreland County Courthouse in Greensburg, PA. I also have John Jr.'s will dated 29 September 1836. The will lists 18 of his 20 children from his first wife and Annabel Wasson. I have your Maria shown to be, Moriah, in my records. I descend from John's son Joseph, also from Centre Twp, Butler Co., PA. Advise if you want to share info.
