Parisii
The Parisii (or Quarisii) were a Celtic people that lived on the banks of the river Seine (in Latin, Sequana) in Gaul from the middle of the third century B.C. until the Roman era.Their chief city (oppidum) was Lutetia Parisiorum, which later became an important city in the Roman province of Gallia Lugdunensis and ultimately the modern city of Paris. (The name Paris is derived from Parisii).
With the Suessiones, the Parisii participated in the general rising of Vercingetorix against Julius Caesar in 52 B.C. In a battle near the Champ de Mars (the present site of the Eiffel Tower), the Celtic army was soundly beaten and Vercingetorix captured; thereafter the Parisii specifically and Gaul generally were firmly under Roman rule.
It is not known if the Parisii tribe of East Yorkshire and Humberside in Britain was comprised of emigrants from the tribe of the same name based in Gaul. The burial processes of the Gallic and Briton tribes differed.
There is some speculation that the modern surnames Paris, Parrish, O'Parish, etc. have origins in the Parisii. [1]
