The name 'Thompson' first found in Cumberland,where the family held a family seat from ancient times. Scottish Thomsons were found primarily around the Edinburgh area and the West Marches on the borders. The spelling with a 'p' distinguished them from the Thomsons who were a Scottish Clan,originally known as Thomsone or Thomsonis in early legal documents. The distinguished surname can be found in Scotland. It's derived from the name Thomas,an Aramaic name meaning 'twin' or son of Thomas The motto of the English name Thompson is a war cry- 'Nosce teipsum' which translates 'Know thyself.' The most prevelent motto associated with the border clan was "Honestie is the best policie."

Balázs Déri's opinion :
Salish speaking thompson tribe in America related to duv-ani and others may have founded after their deportationTakhompsó (Te-ak-hom-pes-so'o ) in Aigypt where tepes-so'o tribe may have come from.
Also some of the dinkas descending from Mavu-Lishsa and Duv may have originally belonged here .
