Auguste Jay was the son of Pierre Jay of La Rochelle, Fr. and his wife Judith Francois (married 2-4-1657). Pierre's father was Sylvestre Jay of Poictou, Fr (1570 - inq 11-6-1590) whose wife was Marie de la Barre. Auguste was John Jay's grandfather, and you don't know about this lineage????? I am descended from two of John Jay's sisters and have a "sporting piece" hanging over my fireplace which the first Chief Justice purchased in Spain in 1780.
