Here comes the cavalry?
NOTE: from Wikipedia:
" Carruthers is a placeneme in Dumfriesshire which is said to derive from the Brittonic word "caer" meaning "fort" (as in Caerlaverock castle, not far away) and the personal name Ruther (originally Rhythr or Rydderch). It has been suggested that this comes from King Roderic mentioned by St Adamnan. Locally, the name was pronounced "Cridders"."
The Carruthers of Howmains continued however, until the estate was lost in 1772 when financial disaster struck. But a younger son of the last laird acquired the estate of Dormont in Dumfriesshire which is still held by his descendants.
The surname is now mainly found in Glasgow and Edinburgh. Carruthers is a member of the Armigerous Clans and Families of Scotland ie it has a recognised coat of arms.
