All male members of the family who were destined to a secular career were named Conrad or Henry. Emperor Conrad II's grandfather, Otto of Worms, established this tradition in the late 10th century. He named his eldest son, Henry of Worms, after his maternal great-grandfather, King Henry the Fowler; and he gave the name of his father, Conrad the Red, to one of his younger sons, Conrad of Carinthia. Conrad the Red was most probably named for King Conrad I of Germany.
