The name Percy originated in France. It means piercing the valley which also can mean fighting the lower side, the evil side, to reach justice. Jackson means son of Jack. I know, I don't get it either.
ONE theory is that the name was taken from George (Geordie) Stephenson, the mining and railway engineer who hailed from the north-east. Another is that it derives from a term of abuse coined by the Scottish Jacobites in the 1745 Rebellion because of the defence of the town of Newcastle against them by supporters of King George (Geordie) II. The second theory is more plausible because the term Geordie is properly used for natives of Newcastle only. Others originating from the north-east are Tynesiders (from the towns along the Tyne, from Blaydon and Newburn downstream), Northumbrians, Durhamites (Dunhelmians if you are posh) or Makems (from Sunderland).
