Hugh Capet is the namesake of the French Capetian dynasty, the longest lasting one in French history, with an unbroken line of kings, from 987 to 1328. His descendants have been traced, even in America. It may be difficult to believe, but the records are there.
He was the third Capetian king and born in 1008 and ruled from 1031 to his death in 1060. His reign was overshadowed by William of Normandy, future duke there and the Conqueror of England in 1066.
