I'm still trying to fill in some more information for this page.

There is a Coastal Resort south of Durban in KwaZulu-Natal named Widenham

This happens to be the name of one of my ancestral families in Ireland.
There is an associated light-house,
named Widenham Light on the maritime charts,
that denotes a reef that is recommended
for snorkelling and diving.

If you have any further details concerning
family links in South Africa,
please get in touch with me and I'll respond.
