don't know if someone already brought this up (couldn't find it in the list of forums but sorry if it's already been discussed)
in an interview I read that godric's hollow was named after godric gryffindor. i wonder if this has any significance. did harry's parents have an item that belonged to gryffindor that voldemort wanted for his last horcrux? are the potters descended from godric gryffindor? did they live in gryffindor's old house? or is it just the name of the town they lived in.

maybe harry will find something in godric's hollow that will help him defeat voldemort (remember he used gryffindor's sword in cos to defeat the basilisk and dumbledore told him only a true gryffindor could have pulled that sword out of the sorting hat.)
