Baldwin I of Jerusalem 

Baldwin I was the brother of Godfroi de Boullon (or perhaps Godfrey de Bouillon) who became the first Christian King of Jerusalem. (See "Templars in America" page 13)  This is said to have happened in the year 1100. (See "The Second Messiah" p 73)

He died in 1118 and was replaced by his cousin who became known as King Baldwin II of Jerusalem. (See "The Second Messiah" p 82)
