Over nearly 20 years, Mr. Brown and his associates at the Pocahontas Foundation in Berryville, Virginia, endeavored to compile the definitive genealogy of Pocahontas' descendants. Starting with the Bolling lines, which include the "white," "red" and "blue" Bollings, the Foundation has issued a series of books that carries Pocahontas' descendants down to the present time. The base volume in the series, Pocahontas' Descendants, was originally published in 1985, followed by three volumes of corrections and additions. In 1994 Genealogical Publishing Company reprinted the base volume, along with the first two volumes of corrections and additions, in a single hardback volume. Third Corrections and Additions, published in 1997, is also available from Genealogical Publishing Company. This is the final installments in this series consisting of two separate sections of additions and corrections to the existing canon, contains over 80 pages of changes and revisions, with separate indexes referring to more than 2,800 names.
