The Chauci were a populous Germanic tribe inhabiting the extreme northwestern shore of Germany during Roman times - basically the stretch of coast between Frisia in the west to the Elbe estuary in the east. By the end of the 3rd century CE, they had merged with the Saxons. The geographical region of East Frisia was inhabited in paleolithic times by reindeer hunters of the Hamburg culture. Later there were mesolithic and neolithic settlements of various cultures leading up to the invasion of Germanic tribes belonging to the Ingvaeonic group. Those were Chauci and Frisians. The region between the rivers Ems and Weser was inhabited by the Chauks, who were partly displaced by Frisian expansion after about 500, and were later partially absorbed into the Frisian society. Saxons also settled the region and the East Frisian population of later times is based on a mixture of Frisian and Saxon elements.
Germanicus in 4 AD assumed several military commands leading the army in the campaigns in Pannonia and Dalmatia. After the death of Augustus in 14 AD, the Senate appointed Germanicus commander of the forces in Germania. Germanicus' parents were Nero Claudius Drusus, son of Livia Drusilla, wife of Caesar Augustus, and Antonia Minor, daughter of Marc Antony and Octavia Minor, sister of Caesar Augustus. Claudius was his brother. Germanicus turned kingdoms from the east to Roman Provinces. He subdued the Germanic tribes east of the Rhine and was a general of mutiny toward feuding legions much between Augustus and Tiberius' unpopularity as a Claudian, although one of Rome’s greatest generals, whose campaigns in Pannonia, Illyricum, Rhaetia and Germany laid the foundations for the northern frontier when Gaius Caesar was wounded during a siege in Armenia and died 2 AD. Tiberius was required to adopt his nephew, Germanicus. In the Bible, Tiberius is mentioned by name only once, in Luke 3:1, stating that John the Baptist entered on his public ministry in the fifteenth yeare of his reign.
There were three of four major branches of the Claudian gens at the end of the Republic. Those with the cognomen Nero were prominent patrician senators during the late Republic; they favoured the praenomen Tiberius. The Neros joined the gens Julia when Tiberius Claudius Nero. Ti. Claudius Nero and Livia Drusilla (herself a Claudian Nero through her father Marcus Livius Drusus Claudianus) was adopted by Gaius Julius Caesar Augustus. Those Claudii with the cognomen Marcellus were plebians and had three consuls in three successive years (51-49 BC; two brothers and their first cousin); they favoured the praenomina Gaius and Marcus. Gaius Claudius Marcellus (consul 49 BC) was married to Augustus' sister Octavia Minor and their son was married to Augustus' daughter, Julia the Elder.
The Claudii with the cognomen Pulcher (fem. Pulchra, meaning "beautiful") were patricians and also very prominent in the late republic; they favoured the praenomina Appius (the only family to bear this praenomen) and Publius. A plebian offshoot of this family was created when a Publius Claudius Pulcher had himself adopted by a plebian (for political reasons) and was thereafter known as Publius Clodius; his sister Clodia also adopted this vulgar spelling.
GENS JULIA branches Julius (fem. Julia) is the nomen of the gens Julia, an important patrician family of ancient Rome supposed to have descended from Julus. (Julio-Claudian dynasty - Julia Caesaris). Julii Caesares, all with the 'Julius Caesar' nomen+cognomnen combination, but differing praenomens. Gnaeus Julius Agricola, conqueror of Britannia. Its founder, Augustus, was a Julian through his adoption by his great-uncle, Julius Caesar. Augustus' stepson Tiberius, whom he adopted as his successor, was a Claudian. By early Carolingian time, a Frisian kingdom united the whole area from present-day West Frisia; the Dutch provinces of Friesland and Groningen and part of North Holland, throughout East Frisia up to the river Weser. It was ruled by Radbod, King of the Frisians whose known names, de Bayeux were still mentioned in folk tales until recent times. Radbod attempted to extirpate the religion and free the Frisians from subjucation to the Merovingian kingdom of the Franks. Radbod soon retreated, in 697, to the island of Heligoland in the south-east corner of the North Sea.
