King James III and VIII, de jure King, died on 1 January 1766 and, as the son of the deposed King James II and VII, rightfully claimed the English, Scottish and Irish thrones (as James III of England and Ireland and James VIII of Scotland) from the death of his father in 1701, when he was proclaimed king of England, Scotland and Ireland by his cousin Louis XIV of France. Following his death in 1766 he was succeeded by his son Prince Charles Edward Stuart ("Bonnie Prince Charlie") in the Jacobite Succession.
The White Rose or White Cockade is the symbol of Catholic monarchy all over Europe.
The motto of the family was (in Old French) Aymez Loyaute - "Love Loyalty"- a fitting motto if ever there was one!
God save the House of Stuart!
