There is a old prophesy, “When Tweed and Powsail meet at Merlin’s grave, Scotland and England shall one monarch have.”
In 1567, the very day that James VI of Scots (Son of Queen Mary of Scot and Henry Stuart Darnley) also became the first of England (Shared throne of Scotland, England and Ireland), the River Tweed burst it’s banks at the mouth of the Powsail Burn, at Merlin’s Grave- something it never did before or since.” (A)
