Jam Sahib
Jam Sahib, is the title of the ruling prince of Nawanagar, now known as Jamnagar in Gujarat, an Indian princely state. The Jam Sahebs were from the Jam Jadeja clan, who are a branch of Yaduvanshi Rajput. The name of Jamnagar formerly known as Nawanagar was derived from the same root, while the word Jam itself means Sardar, or King, Saheb is an Arabic term which literally translates to "Owner" or "Proprietor".
