I do not expect this to be put in the entry, for obvious reasons. Neville has an aunt Enid and before I had even heard of Enid Pettigrew, I had a theory that Neville's mom and Peter Pettigrew were siblings. Neville is described as either looking like Peter or looking like his mother Alice (maiden name unknown) - and not looking at all like his grandmother Augusta. Ok, Peter and Alice have very different eyes, want to be on record. (Vaudree (talk) 23:44, October 21, 2015 (UTC))
p. 158 (POA 11) - “Harry slammed the album shut …” / “He watched, as though somebody was playing him a piece of film, Sirius Black blasting Peter Pettigrew (who resembled Neville Longbottom) into a thousand pieces.” / p. 158 (OotP) – “Harry’s stomach, already uncomfortable, clenched as he looked at Alice Longbottom, he knew her round, friendly face very well even though he had never met her, because she was the image of her son, Neville.”
