Pepin, sometimes called Pepin II and Pepin the Middle, was the grandson and namesake of Pepin I the Elder through the marriage of Pepin I's daughter Begga to Ansegisel.[1] He was also the grandfather of Pepin the Short and great-grandfather of Charlemagne. That marriage united the two houses of the Pippinids and the Arnulfings which created what would be called the Carolingian dynasty. Pepin II was probably born in Herstal (Héristal), modern Belgium (where his centre of power lay), whence his byname (sometimes "of Heristal").
