With regard to my adoptive family, I am apologetic to say that they are Muggles. Near the end of Britain's Wizarding War, I was placed with them for my protection, and given the ring to identify myself if necessary. My biological parents subsequently died, failing to inform their relatives of where I had gone, and by the time anyone might have found out, I had become too much attached to my adoptive parents. Despite their lack of magic, they are rather pleasant to live with, and so I did not go out of my way to inform my magical relatives of the situation. In the interest of simplicity, I have told them that the school I wish very much to attend is a Muggle one, and I would appreciate it very much if you did not disabuse them of the inaccurate notion.
