Everything below is what is known about the shield, including what is not.
The shield is the family's own, registered with the South African Bureau of Heraldry on 28 April 1978. The black half-eagle on gold is for the family's Frisian origin. That is the whole of the registered arms: a shield, and by law nothing more, for a family association may register no helm, no wreath and no motto. So the shield stays fixed, and shared.
For generations the family bore a half-eagle and three silver lozenges, believed to be old and theirs. In 1975 the genealogical authorities, the Centraal Bureau voor Genealogie at The Hague and Dr C. Pama at the Cape, established that those were in fact the arms of the old Frisian family Walta, carried in good faith but in error, with no proven descent. The Bond set the old arms aside, and in 1978 registered a corrected shield: the eagle and a single fleur-de-lis, with no lozenges. Why a fleur-de-lis, specifically, no surviving record explains: the Bureau's certificate confirms the blazon it registered, not the Bond's reasons for choosing it.
The 1978 certificate was lettered by hand with a flat pen. That lettering became the family's own font. See how the VDW font was made.
Everything around the shield, the leaves of the wreath and a motto of your own, is yours to add. These are personal, not part of the registered arms. Use them freely.
One line brought the lozenges back, not as Walta's, but as their own. On 19 February 1896 the Braamfontein dynamite explosion took, from that direct line, a mother and her three young daughters: Anna Sophia van der Walt, born Steyn, and her girls Hester, Johanna and Dauwlina, then about fourteen, five and three. The three lozenges are the three girls. A charge that once came to the family by accident was restored on purpose, and given to them.
Your shield is the registered family arms, the same for every van der Walt. Your motto is yours to choose.
Arms are one way to keep a lineage. See how other South Africans keep theirs.
