'Blaze' simply sounds like a re-spelling of 'Blase' or 'Blaise'. It's a very old names, which was probably most popular in England in the 17th century, and is derived from the name of the 4th century martyr, Blasius (the patron saint of woolworkers). The name 'Blaise' is common in Europe, with one of the world's greatest mathematicians, Blaise Pascal, being an obvious example. However the original meaning of the name is none too complimentary; 'blaesus' is Latin for 'lisping'.
I've met a kid called Jorrell. His name seems to be derived from that of Superman's father in the comic books!
Some names only sound odd in certain parts of the country. In Sheffield I taught a lad called Warren Heath. His parents were probably unaware that Warren Heath is an area just outside of Ipswich; it made me smile when I saw an advertising hoarding in Ipswich proclaiming that "Sainsbury's are now building on Warren Heath" ;-)
