I like it that these are not 'real notables', but genealogical authors, researchers and scientists.
However.. there is a great lack of people who worked on Khoi/San, slave, bantu, asian, and all mixed race ancestors, who were often not treated well by history, as their birth, marriage, death was not noted down.
Who would be the notable early/recent collectors of genealogical information about all the 'non-white' peoples?
