Nice stories, missing 2,3 and 4.
Really a shame I only see story 1 under your profile.
Let the Grangers go to Gringots(?), the Goblins might be able to see which house they are from.
Would really be a laugh if it are two old and dead houses with very big vaults.
Heh, with permission from Serius, the Grangers could help Harry with investing in some stuff.
