What does Patrick Henry have to do with Buckingham County?
His connection to the Diuguid family is an excellent answer. Henry and William Diuguid, Jr., founder of Diuguidsville, were first cousins. William Diuguid and Jean Henry, of Aberdeen Scotland, were the parents of Buckingham’s William Diuguid (1717-1764). Jean was a sister of Col. John Henry of Virginia, aunt to Patrick Henry, Patriot, Attorney, and Governor of Virginia. In 1790, William’s half sister, Margaret Donald of Aberdeen, wrote to Patrick Henry giving an account of the connections between the Henry and Diuguid families.
Today, the letter is housed at the Library of Congress in the Personal Correspondence of Patrick Henry. A transcription is included in William Diuguid of Buckingham County, Virginia by Eleanor Harris MacRae.
