The genealogy of the family can also be traced back to other stamvaders including Karl Booysen-Brùndolf, Pierre Joubert (Jaubert) and Jean Durand.
The Booysen coat of arms is green and gold with a bear standing on a helmet holding a bow.
The shield divided into quarters contains another image of the bear holding a bow in the top right segment.
The top left and bottom right segments depict an oak tree with acorns, signifying strength, continuous growth (in mind/wisdom), and fertility.
The bottom left segment is divided once more and is of a five-point star which represents a noble person/divine quality form above.
