Adela of Normandy: Rollo
built 196 days ago
The duchy of Normandy was originated from the county of Rouen, which was given to the Viking chieftain Rollo as a French fief from the king Charles the Simple , 0911. The county expanded during the 10th century and got the name Normandy after the French word for Viking. The title duke is known to have been used by the rulers since 1006. Sixty years later was England conquered by the duke of Normandy. The union with England lasted with a short break until 1204 when Normandy was conquered by the French king and became a part of their royal domains. The title duke of Normandy was thereafter used by the heir to the throne until it was replaced by the more well known title Dauphine.

According to 'Royal Genealogies', the founder of this family was Gerlon who came to Normandy with Rollo. The first couple of generations are not fully secure which has led to some confusion as to the numbering of the different Counts Thibaut (Theobald).

Nordic Viking, according to the Sagas the same as Rollo, who founded the duchy of Normandy 911 AD. He got his name Göngu-Hrólfr, "Hrolf the Walker", owing to the size of his body. He was so large that no horse could carry him. He had to go on foot. After a battle fought at Chartres in 911 between Viking and Frankish armies a peace treaty was signed, if Rollo would agree to settle there and defend the area against other Viking attacks. For some time he kept his word, but soon, Rollo led his followers on further raids deep into the Frankish empire.
