Around 1100 A.D. there was a King called Anangpal, a Tanwar Rajput who ruled over Delhi. He had two daughters Kamladevi and Roopsundari. Kamladevi was married to the King of Ajmer called Someshwar Chauhan. King Someshwar had a son called Prithviraj Chauhan. Roopsundari was married to King Vijaypal of Kanoj. He also had a son named Jaychand. Since King Anangpal had no sons, he adopted Prithviraj Chauhan and declared him to be the successor to the throne of Delhi. King Anangpal gave to his other relations the towns under his jurisdiction. He also gave away Pokran and Phaloji and the surrounding four Jojan land to Dheersinh Tanwar who was a close relation to King Anangpal.
Dheersinhji Tanwar had a son whose name was Ransinhji Tanwar who in turn had two sons called Ajmalji Tanwar and Dhanroopji. Ajmalji married Minaldevi or Minalde, Princess of Jesalmer. After becoming King of Pokran, King Ajmalji had two sons Viramdevji and Ramdevji, Ajmalji’s younger brother Dhanroopji had two daughters Lakshmi (Lasa) and Sugana.
