I have information on Col. Gabriel and would be interested in how you are related. What do you want to know?
He was born in Amelia Co., Va. (now Nottoway Co.),the third child of Gabriel Sr., who alledgedly came over from Wales. It is generally thought that he married Ursula (Thompson?/Mays?).
His children were: Thompson, (Capt.)Gabriel III, Elizabeth, Sarah (Sally), Nathan, Amey,Jennings Mays, Mourning, Tabitha, Jane and Prudence.
Hope this is helpful. Please let me know if you are related.
