Facts and Events
According to Knox’s two major biographers (North Callahan and Thomas Morgan Griffiths), Henry Knox was one of ten boys born to William and Mary Campbell. Only 4 lived to adulthood: John (baptized July 5, 1741), Benjamin (baptized April 7, 1747), Henry (b. July 25, 1750) and William (baptized August 19, 1756). John and Benjamin apparently went to sea, and pretty much disappeared from the historical record – Knox’s personal papers do not contain any correspondence to or from them and very little mention of them, and there are only a couple of instances in contemporary diaries or correspondence of other people that a Knox who might have been one of those sea-faring brothers is mentioned. In 1780, Knox indicated in his correspondence that William and he were the only brothers still living, but it is unclear when the others died.
