Due to language and country Rohit samaj’s name has changed several times. We can see the description of Rohitak Ganrajya (रोहितक गणराज्य) and the resident of their Rohatgi in Mahabharata. The language of that era was very tough which was later be simplified in Rohitki (रोहितकी), Rohatki (रोहतकी) And Rohatgi (रोहतगी) . This caste was destroyed at the time of Chandragupta Vikramaditya. People migrated and spread to other areas like Mathura, Agra, Patilputra(Patna), and the areas near Ganga. In these places, the families remain counted. They started their business or service to save them. East India had taken control over all India by defeating the Mughals. An English historian of that time has mentioned the fort in the “Journal of Francies Buchanan”. I went up to Rohatas by route to Rajghat. The fortress of ‘Rohita’ son of Harishchandra and grandson of Trishanku from Ayodhya- these lines are mentioned in an article. To write these lines, the inscriptions received from Wukhanan (वुखानन ) were thoroughly studied. Later on, the Odissa government has mentioned in its gajat. Therefore, there is evidence of the connection of this fort with the Rohitashva and Harishchandra dynasties. From here the residents were called Rohitvanshi, Rohitak or Rohitaki and later on they were called Rohatgi. Disturbed by the attack of Chandragupta Vikramaditya, Rohatgi was scattered here and there. As per the conditions and requirements of the time, they started to do business and service. Being engaged in business, they were considered as Vaishya. In the present era also they are not capable to establish their identity in North India, Harayana, Bihar due to involvement in the business. The description is given in three pages from the title of Harishchandra in Wikipedia. Apart from this, Sudha Rastogi and Deepak Tyagi have also published their research paper which could not be obtained.
