Career Jay was described by General John Watts de Peyster as "a perfect specimen of the typical French nobility, pure blood; handsome; well made; graceful; easy, agreeable, and as full of elegant wickedness as an egg of meat. Women, lovely women adored him and of every class; he was a charming fellow; not able but attractive."

According to his obituary, "To all Mr. Jay was a courteous gentleman; but only to those who knew him well and rejoiced in his friendship, were shown in their full strength the true and noble traits of his nature. There was no guile, and no taint of baseness in him. His honor was above the impeachment of even suspicion or malice. The truthfulness, sincerity, frankness, which so beautifully adorned his character, were themselves softened and mellowed by a chivalrous generosity." Together, they resided in Washington,
