Talk:John II, Duke of Schleswig-Holstein-Haderslev

Regnal number
Have never seen him described as John II before, only John the Elder. Is there a reference for the use of a regnal number here? Otherwise perhaps the article should be moved to John the Elder, Duke of Schleswig-Holstein-Haderslev or simply John, Duke of Schleswig-Holstein-Haderslev.Trip Tucker (talk) 04:05, 27 December 2011 (UTC)

Religion
Why would the Catholic nobles of Denmark want him to be King instead of his brother Christian III of Denmark when John himself was raised in Lutheran Prussia?--Queen Elizabeth II&#39;s Little Spy (talk) 08:17, 26 June 2012 (UTC)
