Hi Shannon
Nicholas Cooper Wynne was my paternal grandfather, and he did indeed marry an Erasmus. The sons names were Walter and Eric, but my father - Eamon Anthony, told us that they were his mother's children by a Mr Yeld?
I have also recently been trying to find out about my Grandfather, but with no real success. Owen Edgar and his entire family except his adopted daughter Ann, were drowned in a yachting accident.
Eamon, known as Chucks, is still alive and living in Rondebosch in Cape Town.
My brother, Gavin Cooper Wynne and I both live in Port Elizabeth.
Please let me know if you have any more information at all about this branch of the family.
Janet
