How it is shown: Complete page, without annotations; no crop, no retouch, no search highlight.
Keep in mind: The family recollection of a captaincy is not a documented rank. Likely: the identification of the Chelsea, Vermont pensioner with the Nathaniel Oak born 16 May 1751 (son of John Oake and Susanna Allen) rests on the declaration's age (81 in August 1832), his residence at Winchester, N.H. in 1775 and his witnesses' statements.
