About Theudoald, Mayor of the Palaces of Austrasia & Neustria

He was the designated heir of his grandfather Pépin, but ultimately lost power to his uncle Charles Martel. A spurious genealogy of the Grimaldi family calls him the father of Hugues d'Antibes (c735-810).


Theudoald (or Theodald) was the mayor of the palace, briefly unopposed in 714 until Ragenfrid was acclaimed in Neustria and Charles Martel in Austrasia by the nobles, after the death of his grandfather, Pepin of Heristal. He was the illegitimate son of Grimoald II and Theudesinda of Frisia (Medlands says an Unknown Mistress, not his wife) and thus a grandson of king Radbod. His grandmother Plectrude tried to have him recognised by his grandfather as the legitimate heir to all the Pippinid lands, instead of the illegitimate Charles Martel. His grandmother surrendered on his behalf in 716 to Chilperic II of Neustria and Ragenfrid. He died, probably killed, around 741, after the death of his uncle and protector, Charles Martel. It is notable that, despite his having been proclaimed heir to Pepin the Middle, when Charles Martel seized power, he allowed his nephew to live, instead of killing him, as was the wont in the Middle Ages.


THEODALD ([707/08]-killed 741). The Liber Historiæ Francorum names "Grimoaldus…filium ex concubina Theudoaldo"[143]. The Annales Metense name "Grimoaldi filium eius parvulum ex concubina nata nomine Theodaldum" when recording his appointment as maior domus for King Dagobert II[144]. He was legitimate according to the Monumenta Epternacensia which names "Theodaldum, filium Grimoaldi…ex Theodesina filia regis Rabodi"[145]. After the death of his father, his grandfather Pépin chose Theodald as his heir although he was still a child. His paternal grandmother appointed him maior domus in Austrasia in 714. The Liber Historiæ Francorum records that "Theudoaldo" was appointed maior domus after "Ragamfredo" fled[146]. He was opposed by his uncle Charles "Martel", but fled after the battle of Compiègne 26 Sep 715[147]. The Annales Alammanici record in 741 that "Theodaldus interfectus est"[148].
