This past weekend I visited my Mother's childhood home at Boschoek farm, Potchefstroom, where my cousin still lives today. We visited a very old grave site close to the now Boschoek homestead at Rooi Wal and found the grave of Daniel Cornelius Wehncke's wife Debora Wehncke nee De Vries who was shot by the British during the ABW and it has been told over many Gouws generations that the original homestead at Boschoek was burnt to the ground and had to be rebuilt. My great Aunt lived in this house for many years as did my cousin. I have a photo of the grave and more information on the broader families Wencke / De Vries that I researched after finding this grave; should you still be interested. I notice your query was three years ago.
