My GFx5 also Stewart Grafton (who apparently immigrated to Upper Canada in 1812 from SC). GFx4 is James W. Grafton; b. Jan 4th, 1798 Fairfield County, SC d. Feb 9th, 1863 Barton Twp. (Hamilton), UC.

My partial copy of the Grafton Family Connection stops with Thomas and Elizabeth. You seem to have more information than the authors did.
