Five Harry Potter questions?

i have the answer to why harry's eye color is important but nothing else....godric gryfindor's eyes are green. and even though lily is muggle born, muggle borns always have a wizard descendant very far back....i was wondering the same thing and i asked my friend, this is what she said and i think she said she also got it off of mugglenet..or one of those other website...about the other questions sorry but i have no idea. hope this helps
