William the Conqueror's real last name was "Bastard," as he was born illegitimate. He was the son of Robert I, Duke of Normandy, and his mistress, Herleva. Although he is commonly referred to as William the Conqueror, his title reflects his significant military achievement in the Norman Conquest of England in 1066 rather than a surname. After becoming king, he established the Norman dynasty in England.
Currently his name is William; i don't know his last name.
