Robert Bolling Batte compiled an extensive collection of genealogical and historical research notes and files. In the key to the sources a letter indicates the type of document and the number indicates either the county or a specific item. For example, A3 stands for Petersburg birth registers, B23 stands for Charles Washington Friend Bible, and P81 stands for the published title Rebirth of the Old Dominion. (A = birth register, 3 = Petersburg; B = family Bible, 23 = Charles Washington Friend Bible; P = publication, 81 = Rebirth of the Old Dominion.). The collection is held by the Library of Virgina and accessible at: www.lva.virginia.gov/whatwehave/bio/BA.html
