Sien sy doopinskrywing hierby aangeheg, en die inventaris van sy ma, Anna Hasselaar.
Daar is 'n nota op Richard Ball se website: Notes: In 1798, in the Estate accounts of his wife' sister, Anna [Clara] Bok, are listed 5 sons, Andries, Christiaan, Paul and Jacobus Bester, all already dead but leaving offspring who are named, and Nicolaas Bester, still living at that date.
Geen van Andreas Bester se ander kinders tree op as doopgetuies by Casper se kinders se dope nie, wel Isabella Engels en Willem Engels, sy halfbroer en -suster.
