I have a copy of the original document from the Library of Virginia and quote it in the Bass family history on my site. It is not a bible record but rather an unofficial paper written for William Bass by the county clerk, "saying that he was not a "Negroe or Mulattoe" as his neighbors thought.
The genealogy the clerk wrote is a nonsensical version of his family history which is completely refuted by the actual Bass family bible and family records published by Alfred Bell who was allowed to view them for his book published in 1961. (The family now refuses to allow anyone to see them).
However, that does not matter because William's genealogy is also recorded in the Norfolk County wills, deeds, tax lists and court records.
There was no such person as Symon Lovina.
William was the great-great grandson of John Bass and Keziah Elizabeth Tucker, an Indian woman--the only documented Indian in William's family. And he was the grandson of Sarah Lovina/ Leviner, the daughter of a "Negro" slave.
