I have the following South African Jacobs connection:
My Grandmother was Elizabeth (or Elizabetta) Helena De Beer
According to my father, her mother's maiden name was Neeltjie (or 'Cornelia') Elizabeth Philippina Jacobs.
Neeltjie married a Matthys Christoffel Johannes De Beer in 1909 when she was around 21 so she was born about 1888.
I am looking to trace the Jacobs connection and any information anyone might have would be greatly appreciated.
