Hi 
I am delurking to ask a question that I have wondered about for a while.
We Know that Sirius went to stay with James at his parents house, but 
we never find out what happened to James's parents. Were they alive 
when Harry was born ?
Were they alive whan James and Lily died/ If so why did they not make 
contact with Harry or take him in to bring up?

Any theories anyone
