LILY AND DUMBLEDORE
In Chamber of Secrets on page 245 it mentions Dumbledore's hair as being Auburn which is a shade of red. In Chamber of Secrets when Harry looks into the Mirror of Erised it says Lilly, Harry's mother, hair color as red. Now, since they both have reddish hair color (and note most people dont) could there possibley be a relationship going on here? Possibley Dumbledore being Lily's Father? They have not mentioned her maiden name before in the books. Although I have read once before that JK Rowling said her maiden name was "Evans" she could have changed it and if not her Dumbledore could have because they didn't want anyone to know or put Lily into some sort of danger.
Albus Dumbledore is the one wizard Voldermort always feared. So I have another Idea why Harry was attemptedto be killed by Voldemort. Voldemort did not come to the Potters to kill lily or James. From some facts we are given it leads to he only came to kil Harry possibley knowing he has extrodinary powers like Dumbledore and wanted to kill Harry off before he could grow up and learn magic. James was going to stand up to Voldemort. It said Voldemort would kill anyone who tried to stand up to him. Thats why James died. Now for Lilly. Voldemort said to her "Move aside Silly girl" basically meaning "I wont kill you but let me kill Harry and I will leave you alone."
