Bloodline of the Serpent Seed

In Abrahamic religions, fallen angels are angels who had sinned, when according to Genesis the sons of God had mated with the daughters of men and had offspring by them. The Serpent Seed doctrine is the teaching that in the Garden of Eden, the serpent (the devil, or adversary) had intimate relations with Eve.
The Merovingians were a dynasty of Frankish kings who ruled a frequently fluctuating area, largely corresponding to ancient Gaul, from the fifth to the eighth century. Gaul was a historical region of Western Europe during the Iron Age that was inhabited by Celtic tribes, encompassing present day France, Luxembourg, Belgium, most of Switzerland, and parts of Northern Italy, Netherlands, and Germany, particularly the west bank of the Rhine.
They were sometimes referred to as the "long-haired kings", and following the collapse of the Roman Empire, the Merovingian's helped to re-shape the map of Europe and to give stability to the region that would emerge as the country of France.
