Henry Edward Yelverton, 19th Baron Grey de Ruthyn (8 September 1780 – 29 October 1810) was a British peer.
If I wed, I will bring home a Sultana, with half a dozen cities for a dowry, and reconcile you to an Ottoman daughter-in-law, with a bushel of pearls not larger than ostrich eggs, or smaller than walnuts."
Later that year, Byron stayed at Newstead Abbey for the summer whilst Grey was traveling abroad.
He was once my Greatest Friend, my reasons for ceasing that Friendship are such as I cannot explain, not even to you, my Dear Sister, (although were they to be made known to any body, you would be the first) but they will ever remain hidden in my own breast."
Byron wrote again to his sister of his troubles with his mother: "all our disputes have been lately heightened by my one with that object of my cordial, deliberate detestation, Lord Grey de Ruthyn."
