Lightgoddess, you have Sev's birth year wrong. It's 1959 according to Mugglenet and 1958/?/1959 according to HP Lexicon, so I went with 1959. I also went a bit different with the names...

Rune
(Equivalent of "Severus Snape")
Fehu represents cattle the Norse symbol of wealth. This rune has some interesting implications based on the fact that cattle, unlike land, move about of their own accord. Cattle also reproduce, so this rune often speaks of wealth that renews or perpetuates itself. Wealth takes many forms, but this rune generally represents the value that is purely material or monetary in nature. Alternatively, this rune is deeply associated with Frey, and hence can be the harbinger of fertility and children.
