Giovanni Raciti - Cimbri or Frisian?
The Danish Vikings (and possibly some Jutes who arrived in Kent, Hampshire, and the Isle of Wight circa 449 AD) who settled in the English Danelaw doubtless included Cimbri descendants from the Limfjord in Himmerland. In addition to providing detailed archaeological, historical and linguistic data to provide a chronological perspective relating to the Cimbri and their associates the Teutones, a recent study  focuses on genetic data. The Y-chromosome "signatures" of some from the Danish speaking area of the Danelaw (but not elsewhere in England or in Ireland at all), as well as regions believed to be settled by the Cimbri in Iron Age times (e.g., southeastern Norway), possess the single nucleotide polymorphism marker S28. This marker, which defines the phylogenetic category R1b1c10 is found at highest concentration in the Alpine areas of Germany, Switzerland and Italy and fans out across the area of Central Europe, as far east as Greece, known to have been inhabited by the La Tene Celts.
Frisian marker - R1b1c9, R1b1c9a
The modern remnants of Frisia Magna are small and scattered. Most of it became dominated by its expanding neighbors: the Saxons (who were moving north and west) and the Franks (who were pushing north and east). Western and Middle Frisia are solidly within the modern state of the Netherlands, which now includes the "heartland" of the Frisians from the North Sea coast from Alkmaar in the modern province of Noord-Holland, along the coasts of the modern provinces of Friesland and Groningen, and up to the mouth of the Ems. Culturally, it has shrunk down to the province of Friesland alone. The Frisian language is now spoken there and in parts of the Wadden Sea islands of Terschelling and Schiermonnikoog (West Frisian language), in the German municipality of Saterland (Saterland Frisian language) and in parts of the German district North Frisia (North Frisian) on the west coast of Jutland. The North Frisian language is under heavy pressure from Low German, Standard German and faces possible extinction. A total of 29 schools in Southern Schleswig offer courses in Frisian. The language is not spoken in Denmark. The East Frisian Low Saxon (a dialect of the Low Saxon) is spoken in East Frisia.
The Frisian people also migrated to other areas in Europe. Migrations to England during the early Middle Ages (along with the Angles, Saxons and Jutes) have been particularly well characterized through genetics, linguistics, and archeology.  The Frisian language has much in common with Old English.
In the Faorese island of Suðuroy people refer to 'Frísarnir í Akrabergi' (the Frisians of Akraberg), indicating that the Frisians might have had some sort of settlement there.
