Christopher Wyatt was the father of Leo Wyatt, father-in-law of Lillian, and is the namesake of Chris Halliwell. Little is known of him other than he was a mortal and Leo had a close enough bond with him that he would name his own son after him. However, Leo did not seem to want to talk about him with Piper, saying that he belonged in a different lifetime. Leo later gave a blanket to his eldest son, Wyatt Halliwell, and said that it was his grandmother's. This grandmother could have been Christopher's mother or his mother-in-law. He lived in Burlingame, California.
