He was the youngest son of Henry V, Duke of Mecklenburg, and Helen of the Palatinate, a daughter of Philip, Elector Palatine. As a result of an injury at a tournament he was mentally ill for many years. After Henry V's death in 1552, he lived at the court of Duke Ulrich of Mecklenburg in Güstrow, where he died. Whether he ruled actively is questionable in the light of his disability. He was buried

Louisa was married on 29 December 1803 in Norwich, Norfolk to Godfrey Macdonald, 11th Baronet Macdonald of Slate, later the 3rd Baron Macdonald of Slate. They had three children born before their marriage (legitimized by Scottish law, but not by Irish law) and ten children born after their marriage. (A previous marriage in Scotland was considered of doubtful validity.) These children and their posterity are the only descendants of Prince William, 1st Duke of Gloucester and Edinburgh.
