College of Arms London 10 July 1796
A violent inflammation in my eyes since 1792 hath greatly impeded my general researches and abridged the gratification I should have had in being able to communicate to your Excellency a satisfactory result of my investigations. I am not without hope of again addressing your Excellency on the subject. I shall however now mention that Laurence Washington of Soulgrave in the County of Northampton Esquire married Margaret Daughter of William Butler of Sussex Esquire, & died in December 1616 leaving Issue.
1. Sir William Washington of Packington in the County of Leicester, Knighted in 1618, & died about 1648; having married Anne, half Sister to George Villiers Duke of Buckingham &c. who was killed at Portsmouth by Felton.
2. John. 3 Richard. 4 Laurence. 5. Thomas. & 6. George.
It is probable that the John & Laurence here mentioned were the same John & Laurence who migrated & Settled in America as stated in the Account of the Family which your Excellency did me the Honor to transmit in your Letter of 2 May 1792. Could your Excellency obtain a certain Account of the deaths and ages of John & Laurence respectively, it would probably ascertain the connection; as I am of opinion that they were Sons or Grandsons of the above Laurence Washington & Margaret Butler. Many years ago a Gentleman from America, whose name I do not recollect, produced an old Seal with the Arms of Butler engraved thereon, which he told me he had received from your Excellency. With purest wishes for your Excellency’s felicity I have the honor to Subscribe Your Excellency’s most respectful and most obedient humble Servt
