Question: Who is Grimoald The Younger's paternal grandfather?

Knowledge 1: Grimoald the Younger
Grimoald II  (died 714), called the Younger, was the mayor of the palace of Neustria from 695.He was the second son of Pepin of Herstal and Plectrude and his father placed him in the office of mayor of the palace in the Neustrian kingdom in 695, when he was still young.He married Theudesinda (or Theodelinda), daughter of Radbod, King of the Frisians, and had two sons: Theudoald and Arnold.While en route to visit the tomb of Saint Lambert at Liège, he was assassinated by a certain Rangar, in the employ of his father-in-law.His sons carried on a fight to be recognised as Pepin of Herstal's true heirs, since Grimoald predeceased his father and his half-brother Charles Martel usurped the lands and offices of their father.In short, he was innocent but unlucky. [SEP] Knowledge 2: 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.
