I am also decended from Moses Preston through his son Moses "Coby" Preston. Several years ago, I obtained his Revolutionary War pension file from the National Archives.
Their website, (www.nara.gov
), can instruct you how to order a copy of the file for yourself. The contents should include Moses's petition for a pension and Nathan Preston's
declaration supporting his claim from 1818; an afadavit by Moses in 1828 challenging the suspension of the pension; Fanny Arthur Preston's request to receive Moses's pension
after his death in 1842 and a letter from the County Clerk of Bedford, VA certifying a record of their marriage. There is also a request by Moses's children to transfer his
pension to them after Fanny's death. If you wish to exchange further information with me about our common Preston ancestors, please email me a firstname.lastname@example.org
