I have had an ongoing exchange of Tarbox info with your brother Nick. If you will send me an e-mail address, I will send you my e-book containing the Tarbox line. It is a large Word file. George Roger Tarbox (1882-1967) married Ada Brook Jackson. Ada was the dau of Caleb Jackson and his first wife, Ada Frances Brook. Caleb was the son of Thomas Jackson and Sarah Ann Register. Thomas was the son of Alexander Jackson and his first wife, Sarah Elizabeth Layton. My e-book traces the LAYTON line of Delmarva down through the many generations to today. Sarah E Layton was the dau of Hughlett Layton and his first wife Mary Tilney. Hughlett was the son of Tilghman Layton and Sarah Masten. Tilghman was the son of Louder Layton and Tabitha Laws. Louder was the son of William Louder Layton and Priscilla Lofland.
