Polk

Among the the peoples of ancient Scotland, the first to use the name Polk were the Strathclyde- Britons. Polk was a name for someone who lived at Pollok (Gaelic: Pollag), a large district on the south-western side of the city of Glasgow, home to Crookston Castle, where Mary, Queen of Scots, was once held. The name of the town has Gaelic origins, from the word 'poll', meaning "pool" or "pit".
