And she still remains catholic in Christ's name. Sigebert I (c. 535 – c. 575) was a Frankish king of Austrasia from the death of his father in 561 to his own death. He was the third surviving son out of four of Clotaire I and Ingund. His reign found him mostly occupied with a successful civil war against his half-brother, Chilperic. When Clotaire I died in 
Title: Sigebert II
Content: See Sigeberht II of Essex for the Saxon ruler by that name.  Sigebert II (601 –613) or Sigisbert II, was the illegitimate son of Theuderic II, from whom he inherited the kingdoms of Burgundy and Austrasia in 613. However, he fell under the influence of his great-grandmother, Brunhilda. Warnachar, mayor of the palace of Austrasia had Sigebert brought before a national assembly, where he was proclaimed king by the nobles over both his father's kingdoms. However, when the kingdom was invaded by Clotaire II of Neustria, Warnachar and Rado, mayor of the palace of Burgundy, betrayed Sigebert and Brunhilda and joined with Clotaire, recognising Clotaire as rightful regent and guardian of Sigebert and ordering the army not to oppose the Neustrians. Brunhilda and Sigebert met Clotaire's army on the Aisne, but the Patrician Aletheus, Duke Rocco, and Duke Sigvald deserted her host and Brunhilda and Sigebert were forced to flee, before being taken by Clotaire's men at Lake Neuchâtel. Brunhilda, little Sigebert and Sigebert's younger brother Corbo were executed by Clotaire's orders, and Austrasia and Neustria were reunited under Clotaire's rule, who now ruled the entire kingdom of the Franks.
Title: Sigebert III
Content:  Sigebert was born in 630 as the eldest son of Dagobert I, King of the Franks, and his concubine Ragnetrude. The king recalled and made peace with Saint Amand, who was previously banished for criticizing the king's vices, and asked him to baptize his new-born son. The ceremony was performed at Orléans and Charibert II, Dagobert's half-brother who was King of Aquitaine at the time, was the god-father. Dagobert assigned the education of Sigebert to Pepin of Landen, who was the mayor of the palace in Austrasia under his father Chlotar II, until 629. Pepin took the young Sigebert and moved with him to his 
Title: Sigebert IV
Content:  According to the pseudohistorical Dossiers Secrets d'Henri Lobineau and related documents, Sigebert IV was the son of the Merovingian king Dagobert II who, on the assassination of his father, was rescued by his sister and smuggled to the domain of his mother the (otherwise unknown) Visigoth princess, Giselle de Razès in Rennes-le-Château. He is said to have arrived in the Languedoc in 681 and, at some point, adopted or inherited his uncle's titles, duke of Razès and count of Rhedae. He is also said to have adopted the surname, or nickname, of “Plant-Ard” (subsequently Plantard) from the French appellation ‘rejeton ardent’ ‘ardently flowering shoot’ of the Merovingian vine. Under this name, and under the titles acquired from his uncle, he is said to have perpetuated his lineage. Journalists and scholars who have debunked the Priory of

She was a maiden beautiful in her person, lovely to look at, virtuous and well-behaved, with good sense and a pleasant address. Her father did not refuse, but sent her to the king I have named with great treasures. And the king collected his chief men, made ready a feast, and took her as his wife amid great joy and mirth.

According to Gregory of Tours:  Upon seeing this, his brother Chilperic sent to Athanagild for his other daughter's hand. This daughter, Galswintha, was given him and he abandoned his other wives. However, he soon tired of her and had her murdered in order to marry his mistress Fredegund. Probably spurred by his wife Brunhilda's anger at her sister's murder, Sigebert sought revenge. The two brothers had already been at war, but their hostility now elevated into 
Title: Beuve
Content:  Based on an oral tradition recorded by Flodoard, Canon of Reims, three centuries later, Beuve and her brother Balderic were reputed to be children of a king Sigebert, whom Flodoard identified as Sigebert I, king of Austrasia. Many early historians follow Fodoard in this. However, Christian Settipani finds that this contradicts what is known about Sigebert I. Sigebert is known to have had a son, Childebert II, and daughters Ingund (wife of Hermenegild), Clodesinde, betrothed to Authari, king of the Lombards, then to Reccared, king of the Visigoths and probably a daughter married to Duke Chrodoald. Sigebert I may have had other daughters mentioned by his contemporaries, but the case of an unknown son is much less certain. According to the Salic law, on the death of a 
Title: Dagobert II
Content:  Dagobert was the son of Sigebert III (ruled 632–51/6) and an unknown woman. It is unlikely that he was a son of Sigebert's only known wife, Chimnechild, who survived him. He was thus the half-brother of Bilichild, Chimnechild's daughter by Sigebert. He was named for his grandfather, Dagobert I (623–39). According to the Book of the History of the Franks, which dates to 727, after Sigebert's death, Grimoald, the mayor of the palace and the most powerful official under the king, arranged for Dagobert to be tonsured and placed in the custody of Dido, bishop of Poitiers. Tonsuring rendered Dagobert unfit for the throne, since Merovingian kings always wore their hair long. Dido then sent Dagobert to Ireland. The dating

Title: Sigebert III
Content:  The Mayor of the Palace Grimoald managed to convince the young Sigebert, who was childless at the time, to adopt as his heir Grimoald's son Childebert the Adopted. However, the king married Chimnechild of Burgundy and had a son of his own, the future king Dagobert II. He also had a daughter, Bilichild, the future Queen of Neustria and Burgundy. In 656, after the death of Sigebert, Grimoald attempted to usurp the throne of Austrasia and had the young Dagobert (who was seven years old at the time) tonsured and sent to a monastery in Ireland. Grimoald's son Childebert was proclaimed King of Austrasia in 656, but the reign was short-lived as he was deposed after seven months in 657 and both he and his father were killed in a revolt. Austrasia next passed under the rule
