I find no documentation for any Anne Bacon as daughter of any Nathaniel Bacon, and no documentation for any Anne Le Grosse as wife of any Nathaniel Bacon.
The Thomas Bacon who was a Member of Parliament seem NOT to have been the same person as any Thomas Bacon who emigrated to Virginia. https://www.historyofparliamentonline.org/volume/1660-1690/member/b... - however, there is evidence that the Nathaniel Bacon who emigrated c. 1674 and led the notorious Rebellion in 1676 was in fact the MP's son.
