- Marriage: Ann Tapp
- Died: 1782
John is established as the brother of Thomas, and therefore the son of Adam I, by the contents of his son William's Revolutionary War pension application. - See transcription under William's name.
John apparently served in Captain Michael Reader's militia in Shenandoah County, according to the roster dated 1777. His brother, Walter, also served in this company. However, no record of his service has been found beyond the statements in William's affidavit that he had served as a substitute for his father and also for his Uncle Thomas.
John's wife, Ann, was named the administratrix of his estate on 28 Nov 1782, so presumably he died shortly before then.
John married Ann Tapp.
