Ancestry of Dhunaka
Jat Gotras from Dhunaka
James Todd obtained a Pali inscription about Jit or Jat tribe at village Ramchandrapura 3 kos (6 miles) east of Bundi state, which he sent to Asiatic Society London. The inscription reveals that there was a king Thot born in Uti vansha. His son was Raja Chandrasain, a powerful and beloved of his subject. The son of Chandrasain was Kartika, renowned for his prowess. His wife was Gunaniwas, who gave birth to two sons Mukunda and Daruka. Daruka produced son named Kuhal. Kuhal produced son named Dhunak, who achieved great works. He had war with Hill Meenas tribes and defeated and destroyed them. He along with his brother Dok worshipped gods and brahmanas. They founded a Sun-temple for the pleasure of his beloved wife. The temple will stand till the sumer suvarna mountain stands on the sand. Kuhal had founded this temple and a Maheshwar temple in east. The popularity of this was spread by Achal, son of Mahabali Maharaja Yashovarma. 
The period of war of this dynasty with pahari Meenas is difficult to asses. If we assume that Jat ruler Kartik had war with Menander then the period of this comes about 150 BC. Menander had attacked areas upto Chittor. It is very likely that Kartika had a war with Menander. This way the period of his descendant becomes the first century. If we look into the period of Achal who made this temple popular it comes around third or fourth century or beyond it, as ruler Yashovarman was in Maukhari vansha in eighth century in Kannauj. He had sent a delegation to China in 731 AD.  Lack of records and history prior to sixth century prevents prom determining the exact period of the rule of Kartik and his descendants. According to Thakur Deshraj, We can presume their rule from fourth to sixth century. 
But no final identification has been made so far.
Our effort to identify the name Dhanika referred to in this document takes us to undated James Tod's Inscription No. II: Ram Chandra Pura Inscription of Maharaja Kartik where Dhanuka is mentioned as son of Kuhla. It needs closer examination to finally identify it on the base of texts of both these inscription.
In all probability, both the inscriptions seem to refer to one and the same person; and if this is proved correct, it would solve the riddle about the probable date of undated Inscription No. 2 under reference.
Dabok Inscription of 644 AD
We have a record of 644 AD belonging to the early Guhilas and comes from Dabok, 8 miles east of Udaipur. There is reference to the local ruling family which held the area under one Dhavalappadeva, is made in this form:
"When Shri Dhanika of the family of Guhilaputras was enjoying Dhavagarta"
Dhavagartā being identical with Dhod in Bhilwara district in Rajasthan. This record is concerned with the religious benefaction in the form of akshayanivi or fixed endowment, which constitutes what is called devadāya in the record. The endowment was made for two occasions; For the devadroni of Mahadhideva Mahamaheshvara instituted by the donor Vaidya Giyaka and for another devadroni created by former Vaidya Yashodeva of Shri Durgadevi who had the name Ghattavasini meaning female deity of the pots.
