The Samma dynasty ruled in Sindh and parts of Punjab and Balochistan from 1351-1551 A.D. The Samma dynasty declined and was replaced by the Arghun Dynasty. After the demise of the JAM TAMACHI Samma dynasty the Nawab migrated along with his brothers and tribal members leaving their once thriving land of Nagar-Samma to parts of India and settled in Gujrat. A vast Village in Gujrat is now settled by the descendants of the 4 tribal leaders who were also blood brothers.
Jam Unar was the founder of Samma Dynasty mentioned by Ibn Battuta, the famous travellor from North africa. Jam Unar, the Samma chief, taking advantage of the strained relation between Sumras (Soomra) and the Sultanate of Dehli, defeated the last Sumra rules, son of Dodo, and established Sammatt rulein 752/1351.Jam Banbhiniya had two sone Jam Unar (1333-1352) and Jam juna (1352-1368), than followed by Jam Tamachi, Jam UnarII, Jam Ali Sher, Jam Sanjar, Jam Nizamuddin I, Jam Nizamuddin II and Jam Firuz. From the other son Jam Juna it was followed by Jam Tohachi, Jam Kran, Jam Sikandar, Jam JuanII, Jam Fath, Jam Sikander II,Jam Salah al- Din. This is precisly the origin of Unars from Jam Unar the founder of the dynasty and Junejoes from Jam Juna the younger son.
