*Support move to Gediminas.  Although Gediminas is a somewhat common male first name among Lithuanians, the name Gediminas is only used by Lithuanians.  Any present or future Gediminas would have a surname which would be included in an article title.  The subject of this article, Didysis Kunigaikštis Gediminas, is the most important and probably only Gediminas without a surname likely to have his own first name only encyclopedia article.  Therefore, I conclude an article title "Gediminas" would have no ambiguity.  More common internationally used king's names such as Henry were used in a number of different countries such as England, Germany, and Sweden.  Therefore, for many of these other monarch's names, it is necessary to specify what country they are from; hence an article would be titled Henry I of England to specify which Henry the article is about, especially since surnames were usually not used for monarchs until later in history.  This is not necessary for Gediminas.
