Izelle’s maternal grandfather. The 1951 Verkeerdevlei marriage record — with the original document image attached — gives the date, the place, and certificate number 5. Izelle verified independently that her grandmother was Ammerentia, so the link is family-confirmed as well as record-matched.
The original image is restricted by the holding archive.

Civil marriage record (certificate no. 5) — Pieter Johannes Tait × Ammerentia Petronella Duvenage, 29 December 1951, Verkeerdevlei, Brandfort.
South Africa Civil Marriage Records, 1801–1974. [link]
Same year, same province, both couples: 5 May 1951 Koffiefontein (du Plessis × Meades) and 29 December 1951 Verkeerdevlei (Tait × Duvenage). Without those two OFS weddings, the daughters' side of the family does not exist.
The Tait line climbs seven generations from Pieter Johannes Tait to George Tait (b. 1765) and his father Joshua. Trumbull, Nesbit, Johnston, Barr — the Scottish Borders cluster, full stop.
