I like the cheerful simplicity of
Bridget.
Brigitta,
Bridie and the awful
Bedelia are not to my taste at all.
I very much like
Birgit, and a friend has made me somewhat tolerant of
Britta, but I wouldn't use it. In fact, I wouldn't use
Birgit either, having no
German heritage.
I have personally encountered two South Africans named
Bridgette, which looks like a horrible hybrid and sounds like
Bridget! I've never met a
Brigitte locally, but I feel the same way about it as I do about
Birgit: excellent in its own habitat but inappropriate for my use.
