For the last 2 years (without paying to join these internet geneology sites) I have been passively trying to determine if we are direct descendants of Thorkall the Tall. The Corkill name is said to have been derived from his. He was a Viking who in the 12th century was a right hand man to King Knut during the Viking reign of England an Ireland, etc. I read his wife and sons were exiled to IOM. This I have not been able to confirm. I have gone through hundreds of pages of history during that time. Then the Scots came to Man. The Corkill name at that time was Mac Corkhill
