Arnulf dies in Regensburg in 937 and is buried at St. Emmeram's Abbey.

Many believe Arnulf was married to Judith of Friuli, daughter of Count Eberhard of Friuli and Gisela of Verona.

The dates, however, do not match up.

Judith of Friuli died around 881.

This would have made a marriage between a boy (or at least young) Arnulf and an elder Judith, who was supposed to have produced several children twenty-three years or so after her death.

More likely, therefore, is that he was married to Judith of Sulichgau (born in about 888), daughter of Eberhard of Sulichgau.

Arnulf's eldest daughter, Judith, will in 948 marry Henry, the second son of the German King Henry the Fowler and his wife Matilda, and through this marriage the Duchy of Bavaria will enter the growing Kingdom of Germany.
