Cunobelinus

Later derivations include Welsh Cynfelyn and Saxon Cynebell, sometimes assimilated to Cynebill (Cyne- akin, royal + bill a type of sword or agricultural tool similar to a machete or woodman's pal). Cynebell in modern English is Kimble, (Chenebelle in Norman English), found in the names of Great Kimble, Little Kimble and Kimblewick, three closely situated settlements in Buckinghamshire. The area has no connection with the historic Cunobellinos, but seems to have been named for a later thane named Cunobell or Cynebell.

Cunobelinus was originally of the Catuvellauni tribe, son of Tasciovanus. Despite being mythologised, he was primarily king of the Catuvellauni, whose civilisation centred around Verlamion, modern day St Albans, in the South East of England. He may have been an influence for Shakespeare's Cymbeline, and is referenced in Geoffrey of Monmouth's Historia Regum Britanniae and Raphael Holinshed's Chronicles.

I believe that the original form of this name was Cunobelinos, not Cunobelinus (which would be a Latinized form).
