NB. Dark grey denotes a sovereign, all of which were crowned with the exception of Edward VIII. When a successor has been a distant relative, a bold border indicates from whom the Crown was passed, whilst the dotted border shows to whom it was passed. Where there has been multiple marriages, e.g. Henry VIII, only those that produced children with a direct impact upon the Line of Succession have been included.
