Demelza
its pronounced the way it is spelt, it is unusual ( never met another yet) and flows nicely, although my parents weren't able to find a middle name to rhyme. Nicknames -there are many but all are along the lines of - De, melzi, mel, melza, demi etc. Name origin - Welsh/Polish, from the movie series Poldark, Demelza being one of the main charactors. Female.
