Family and children

Although never Emperor, Otto's father Henry I the Fowler is considered the founder of the Ottonian dynasty. In relation to the other members of his dynasty, Otto I was the son of Henry I, father of Otto II, grandfather of Otto III, and great-uncle to Henry II. The Ottonians would rule Germany (later the Holy Roman Empire) for over a century from 919 until 1024.

Otto had two wives and at least seven children, one of which was illegitimate.
