Halliday Surname Origin
'Holy-day.' It is said this name had its origin in the Slogan, or war-cry of a Gaelic clan residing in Annandale, who made frequent raids on the English border. On these occasions they employed the war-cry of 'A holy-day,' every day, in their estimation, being holy, that was spent in ravaging the enemy's country.
