, this type of crown was used as a symbol by many continental sovereigns, princes, dukes and so on. Many of such persons were named "H", Henry, Heinrich, Harald and so on. Most of the European nobility were related in one or several ways to Queen Victoria and other British nobility. Remember, until 1915 the House of Windsor was called House of Saxe-Coburg-Gotha after the prince consort Albert.
