I am not a direct descendant of the Gaffs but Jonathan Gaff's son, Thomas 1785 of Cawston married Ann Baxter b1789. Thomas was brother of John, Jonathan, and Elizabeth.
Ann Baxter was sister to my third great grandmother, Mary Baxter.
I have done some research forward on Thomas's line and am quite happy to share and compare. I have got stuck on one or two of the children of Thomas and Ann.
