• Coenraad Willem De Buys (born estimated: 1870) who was married to Elsie Susanna De Beer and had Joseph Benoni De Buys (born 09/03/1895, died 10/05/1945)

• Willem Frederick De Buys who was married to Isabella Maria Labuschagne (born 02/1894, died 12/09/1959).  Isabella had Sophia, Levina, Isabella and Martin Rood from a previous marriage to a Rood.

I have a little more information on each of these families but will not share for privacy reasons and to allow me to verify any information I receive on these De Buys'.

Where dates have been "estimated" I have merely set the date of birth around 25 years before the birth of the child, I therefore, could be badly out.

If you know these families, or other De Buys families who's information you think I may not have please feel free to get in touch with me.
