Question: Who is Pepin Of Herstal's paternal grandfather?

Knowledge 1: Pepin of Herstal
Pepin II (c. 635 – 16 December 714), commonly known as Pepin of Herstal, was a Frankish statesman and military leader who de facto ruled Francia as the Mayor of the Palace from 680 until his death.He took the title Duke and Prince of the Franks upon his conquest of all the Frankish realms.The son of the powerful Frankish statesman Ansegisel, Pepin worked to establish his family, the Pippinids, as the strongest in Francia.He became Mayor of the Palace in Austrasia in 680.Pepin subsequently embarked on several wars to expand his power.He united all the Frankish realms by the conquests of Neustria and Burgundy in 687.In foreign conflicts, Pepin increased the power of the Franks by his subjugation of the Alemanni, the Frisians, and the Franconians.He also began the process of evangelisation in Germany.Pepin's statesmanship was notable for the further diminution of Merovingian royal authority, and for the acceptance of the undisputed right to rule for his family.Therefore, Pepin was able to name as heir his grandson Theudoald.But this was not accepted by his powerful son Charles Martel, leading to a civil war after his death in which the latter emerged victorious.

Ansegisel (c. 602 or 610 – murdered before 679 or 662) was the younger son of Saint Arnulf, bishop of Metz.He served King Sigebert III of Austrasia (634–656) as a duke (Latin "dux", a military leader) and "domesticus".He was killed sometime before 679, slain in a feud by his enemy Gundewin.Through his son Pepin, Ansegisel's descendants would eventually become Frankish kings and rule over the Carolingian Empire.

[SEP] Knowledge 2: Childebert the Adopted
Childebert III the Adopted(" Childebertus Adoptivus") was a Frankish king.Childebert was a son of the Mayor of the Palace Grimoald the Elder.He was thus a grandson of Pepin of Landen.He was adopted by King Sigebert III and Queen Chimnechild.When Sigebert III died in 656, Grimoald had Sigebert ’s biological son Dagobert II shorn of hair and sent him to an Irish monastery and then proclaimed Childebert king of Austrasia.Grimoald, Childebert and Ansegisel( who had married the daughter of Pepin of Landen) were finally seized and turned over to the king of Neustria, Clovis II, who had them killed.There are two differing accounts of his death, however.Either Clovis and his mayor of the palace, Erchinoald, captured and executed him in 657 or Chlothar III annexed Austrasia in 661, deposing the young usurper and executing them both the next year.The family reappeared in politics with the rise of Ansegisel ’s son, Pepin of Herstal.
