Not info exactly ... but I was at school with a girl (also respectable!) named Duprecia (dyou PREE sha) whose name I take to be a feminised surname. There are a good number of people with French surnames in South Africa - we owe our wine industry to their ancestors, the Huguenots - and this one would be Du Pré in French but Du Preez here.
It isn't much of a stride from Du Preez to Depreece, though the -z on Du Preez is silent. But that didn't stop Duprecia's parents!
