Will of John Campbell (ca. 1789-1866), Treasurer of the United States

I have never found any documentary evidence which establishes the exact dates of birth or death for this John Campbell. His will, dated 25 April 1865, was probated in Washington County VA on 28 February 1867. [See Washington County VA, Will Book 17, pages 214-215.] In the will, John leaves his personal and real property to his brother Arthur for the duration of Arthur's natural life. After Arthur's death, the residue of John's property is to go to his nephew, Joseph T. [Trigg] Campbell. Joseph is named executor [Comment: Joseph Trigg Campbell was a son of John's brother, Edward Campbell]. A facsimile of the probate certification is shown below:
