Why it’s called “Scottish”

The surname Weir has been closely tied to Scotland since at least the early 15th century. It appears in Scottish records, clan histories, and local place-names, and today it is still most commonly found in Scotland, the UK, and the United States due to Scottish migration.

In Scotland, there is a recognized Clan Weir , with principal families such as the Weirs of Blackwood in Lanarkshire. Famous Scottish bearers include footballer Caroline Weir , highlighting the name’s ongoing presence in modern Scottish culture.

Where the name actually comes from

The story behind “Weir” is a bit layered:

  1. Norman origin
    • The name is linked to the Norman de Vere family, originally from places called Vere in Normandy (Calvados, Manche, etc.).
 * “Vere” itself comes from a Norse word _ver_ meaning “station” or “place,” reflecting Viking influence in Normandy.
  1. Old English / Middle English origin
    • Independently, “weir” comes from Old English wer , meaning a dam , fish trap , or water barrier across a river.
 * As a surname, it was often a **topographic name** for someone who lived near or worked with such structures.

Because both traditions landed in Scotland, the name became “Scottish” in culture even though its roots are Norman and Old English.

How it appears in Ireland

In Ireland, some families anglicized Gaelic names as Weir :

  • From Mac an Mhaoir (“son of the steward”) in County Armagh, sometimes rendered as MacMoyer and later Weir.
  • From Mac Giolla Uidhir , also in Armagh, which has been anglicized as Weir, MacClure, or MacGillaweer.

So in Ireland, “Weir” can sometimes be a Gaelic-derived name rather than a direct import from Scotland or Normandy.
