One is based in the USA
One is based in Scotland
Having read the websites which are run by both groups the recommendation is that the one in Scotland seems to be the one which best represents the Carruthers

These recommended sites are
Official Clan site of Carruthers authorised by their hereditary Chief- Carruthers of Holmains
