Blodwyn Bludd (b. 1923) was a vampire singer with a bass-baritone voice. He was known as the "Vampire from the Valleys" and was famous for singing to people before biting their neck.
Behind the scenes
Bludd might be from Wales, as he is known as the "Vampire from the Valleys".
The name is clearly constructed primarily as a play on sanguine sounds, since "Blodwyn" is a girl's name and means "flower white/blessed" in Welsh. The surname, using correct Welsh pronunciation, would lose its vampiric association by sound as it would be pronounced "Bleeth" (th as in 'the', not as in 'teeth').
