Interestingly, I posted some information on His Excellency just yesterday. You may want to review it HERE.
You should also add to your list of noted Strangites the names of Joseph Smith's widow Emma, his four sons, his mother Lucy Mack Smith, his brother William, and his sisters (only one of whom you noted). All of these individuals left the Utah Mormons and proclaimed (for a while at least) this sect the one true Mormon Church and King James Strang the only valid Prophet, Seer and Revelator successor to Joseph.
Finally, I noted your reference to His Majesty's royal title. As near as I can tell, the Mormon Prophet was actually recognized by the U.S. Congress as a king – the only person so honored in our country's history. I would be glad to share the story upon request.
What did the Mormons ever do to you personally I would like to know?
