Pepin of Landen
Arnulf gave distinguished service at the Austrasian court under Theudebert II. He distinguished himself both as a military commander and in the civil administration; at one time he had under his care six distinct provinces. Arnulf was married ca 596 to a noblewoman whom later sources give the name of Dode or Doda, (born ca 584), the paternal aunt of Saint Glodesind of France, an abbess of a convent in Metz. Chlodulf of Metz was their oldest son, but more important is his second son Ansegisel, who married Begga daughter of Pepin I, Pepin of Landen. Arnulf is thus the male-line grandfather of Pepin of Herstal, great-grandfather of Charles Martel and 3rd great-grandfather of Charlemagne.
