High Quality Content by WIKIPEDIA articles! The Aleramici were a medieval family of Italian nobility which ruled various northwestern counties and marches from the tenth to the 14th century. The founder of the family was William I of Montferrat, a Frank, who came over to Italy in 888 or 889 to aid his fellow Frank Guy III of Spoleto in a quest for the Iron Crown of Lombardy. His son Aleram was the first to carry the title marchio or margrave.
