Jats in the period under discussion were Buddhists or Nagavanshis and followers of Shiva. The priestly class would not appreciate to glorify Jats. Jats have been associated with Shiva and even they are said to be originated from Shiva. We will have to search facts from mythology also. One of the name of Shiva is Jati. Many other names are same as many Jat clans. You can see all thousand names here - http://www.jatland.com/home/Shiva#Sh...thousand_names
Other names of Shiva which contain Jat are - Jatadhara, Jatila, Jatukarna
There is a temple of Jateshwara Mahadeva (जटेश्वर महादेव) in Ujjain in Madhya Pradesh.
Here Jateshwara means the Jat God or Jat King.
There is diety named Jateshwara in the cave temple of Kalpeshwar. Kalpeshwar is the place where Shiva's jata appeared. At this small stone temple, approached through a cave passage, the matted tress (jata) of Lord Shiva is worshipped. Hence, Lord Shiva is also called as Jatadhar or Jateshwar. The Kalpeshwar temple is located in the Urgam valley of the Himalayan mountain range near Urgam village (2 km) short of the temple). On the bridle path from Helang to Kalpeshwar, the enchanting confluence of the Alaknanda and Kalpganga rivers is seen. Kalp Ganga river flows through the Urgam valley. The Urgam valley is a dense forest area.
Noe let us come to Inscriptions where Jateshwara is The Nagavanshi Jat King.
We have - Bilaigarh Plates of Prithvideva II : Kalachuri year 896 (1144 AD)
You can read it here - http://www.archive.org/stream/corpus.../n235/mode/2up
Reference - Corpus Inscriptionium Indicarium Vol IV Part 2 Inscriptions of the Kalachuri-Chedi Era, Vasudev Vishnu Mirashi, 1905, p. 551-554
This inscription is of Prithvideva II from Kalachuris of Ratanpur mentions about a Naga Ruler named Jateshwara in Chakrakota.
Chakrakota bas been identified with the central portion of the former Bastar State in Chhattisgarh.
We also have Ratanpur stone inscription of of Prithvideva II : Kalachuri year 915 (1163 AD)
Reference - Corpus Inscriptionium Indicarium Vol IV Part 2 Inscriptions of the Kalachuri-Chedi Era, Vasudev Vishnu Mirashi, 1905, p. 501

The inscription opens with the customary obeisance to Siva, which is followed by three verses invoking the blessings of the deity. The next verse describes Sesha, the lord of serpents Verses 5-8 eulogise the Talahari-mandala which is called an ornament of the earth.
The only point of historical interest mentioned in the extant portion is that he obtained a victory over Jatesvara who is evidently identical with the homonyms son of Anantavarman Chôdaganga.
Kharod stone Inscription of Ratnadeva II : Chedi year 933 (1181 AD)
Reference - Corpus Inscriptionium Indicarium Vol IV Part 2 Inscriptions of the Kalachuri-Chedi Era, Vasudev Vishnu Mirashi, 1905, p. 533
See at - http://www.archive.org/stream/corpus.../n213/mode/2up
The inscription refers itself to the reign of Ratnadëva III of the Kalachuri Dynasty of Ratanpur in Chhattisgarh.
Prithvîdëva II's victory over Jatesvara, the son of Chôdaganga, is next mentioned in verse 18. Unfortunately this verse is partially effaced, but my reading of the preserved portion shows that Prithvîdëva II not only defeated Jateshvara, but even made him captive. This decisive victory of Prithvîdëva II is referred to in the Ratanpur inscription of K. 915 also.
It was engraved by Jâtû. The Srështhin Ralhaṇa, who was the officer in charge of teligious endowments, supervised the work.
In these Inscriptions Jateshwara is not a mythical figure but a King.
We find in above Inscription person named Jatu. Now Jatu is used for Jatrana Jats.
