Wow. I was are there was "slight" boundary change between Westmoreland and Northumberland Counties in 1664, but I had no idea to its extent. Going through the back-issues of *The Bulletin of the Northumberland County Historical Society" I find an article in the 1979 magazine titled "Early English Settlers On Machodac Creek in Westmoreland County" written by Rev. George William Belae (1842-1921) "seventy five years ago" (i.e., 1904). In a footnote by the editor, it is noted "Dr. Beale failed to point out that these 'early settlers' were originally Northumbrians. Even after the formation of Westmorelan County in 1653, the boundary of Northumberland stretched to Machodoc Creek. It is thought that this was arranged through the influence of Col. Richard Lee so that his 'Machotic' lands remained in Northumberland. After his death in 1664, the boundary was lowered from Machodoc to Hamton Hall Creek, a branch of the Yeocomico River." There is not authorship to this "Editorial Note." The editor of this magazine is not given, but it was almost certainly J. Motley Booker or his close friend, Dr. James F. Lewis who were the stalwarts of the NNCHS at the time, and frequent contributors to the magazine's content. Interesting, to say the least. Craig Kilby
