Pepin of Landen
Gertrude's father, Pepin of Landen (Pippin the Elder), a nobleman from east Francia, had been instrumental in persuading King Clothar II to crown his son, Dagobert I, as the King of Austrasia. Due to her position at the palace, Gertrude's mother, Itta of Metz, was likely acquainted with St. Amandus, the Bishop of Maastricht.
