Dumbledores house and a little of Snape

Is there any actually evidence, canon or interview, that sates that 
Dumbledore was in Gryffindor?  I know it seems the obvious choice but 
I am sure it is never stated clearly in the books.  Hagrid does 
mention that "they say" Dumbledore was in Gryffindor but I am a 
little apprehensive as taking this a hard truth.

Anyway the only other house that I could see Dumbledore being in is 
Hufflepuff.  The only reason being is that he is very forgiving and 
gives people second chances.  The Hufflepuff ghost (the fat friar, I 
believe) is constantly trying to give Peeves a second chance but the 
Bloody Baron (Slytherin ghost) will have none of it.

This led me to think of Snape.  I believe that he is so mean 
partially because he can't forgive himself for what he has done as a 
DE and, if he were in Dumbledores position, would not believe his 
redemption for a second.  That is why he respects Dumbledor so much 
but also gets so annoyed at him as well.  I can see Snape being 
completely mystified by unconditional trust.
