Thanks for your input about Bregje.
I should really have checked this before I posted, but I found this interview with Behati Prinsloo:
http://www.youtube.com/watch?v=DXaXVJDP9YEShe pronounces her name bay-AH-tee and says it means "blessed" in
German. Perhaps she means it's a variant of
Beate or
Beatrice or somesuch. I was wondering if it was a traditional Afrikaans or Dutch form of
Beate, but it seems not to be.
