Since he is not my direct ancestor, I haven't really spent any time looking into him. I have, however, looked into the Stewarts in general and have alot of information on them. The book written by Oren F. Morton in 1917 called 'Annals of Bath County Virginia' is incredibly helpful. It is available for free on Internet Archive, Worldcat, Familysearch, and also on Ancestry if you have a subscription there. Though it has Bath County in its title, it covers records and historical accounts in Augusta primarily.
