Lupin's crazy parents / names of teachers

Who would give their child a name like Remus if his surname is 
Lupin?.. Crazy! Quite some coincidence then that a person with such a 
name gets bitten and becomes a werewolf...

Then again, sometimes coincidences like these do happen; when I was 
in high school, the teacher of the subject where you learn to cook 
(forgive me but English is my third language so I don't know what 
it's called ; ))... was called Mrs. Carne, and the teacher of the 
subject where you learn to make objects of tree was called Mr. Hammer.

But anyway I wonder why JKR has made some of the character names so 
obvious, like Hooch, Sprout, Albus... (Albus! He didn't always have 
white hair!). Like their names would be their destiny or something. 
Aaargh! I find that annoying.

Cheers!
