Mr. Bush is seldom wrong but in this case the headline writer and Mr. Bush were both mistaken about disclosing the location of Tyson’s Mill, but certainly correct about the meagerness of the old records. For my version of this mill’s history, see Tyson’s Mill at Headquarters.
Headquarters
HEADQUARTERS, once also known as Grover, has a long history, going back to the 1730s when the area was first being settled. Samuel Green acquired hundreds of acres here, around 1710, and provided his daughters and their families with large plantations of their own, in particular, John Opdycke and wife Margaret Green.
Tyson’s Mill at Headquarters
Modified from part of an article first published in The Delaware Township Post, July 21, 2006, as “A History of Headquarters Mill.”
John Opdycke sold Headquarters Mill to Joseph Howell in 1763, at the end of the French and Indian War. This was probably a shrewd decision on Opdycke’s part, since demand for flour would certainly drop off with the end of the war.
Who Saw George Washington?
The question of whether Washington actually visited Headquarters has bedeviled local historians for decades. The source of the controversy was Fanny Carrell, who was interviewed by Charles W. Opdycke, for his well-known Opdyke Genealogy sometime around 1880 [pg 218-19]. Frances ‘Fanny’ Opdycke was the wife of James Carrell, and he was the grandson of Elizabeth Opdycke Arnwine, daughter of old John Opdycke Esq.
