BENSON family emigrated to South Africa

[webb1e]

Hello listers,

My great-grandmother was Amelia Priscilla BENSON, probably born about 1860 (estimated from husband's bith date). Family rumour has it that her family emigrated from Ireland (no further details) to South Africa. I don't know if she was born in Ireland or South Africa, nor do I know her parents' names.
If anyone has any information about any BENSON emigrating to South Africa in the 1800s, I'd be grateful.

Thanks very much,

John
