The Agni-kunda Legend
The Agni-kunda legend is the best-known traditional account that deals with the origin of the rajputs. This account begins with the puranic legend wherein the traditional kshatriyas of the land were exterminated by Parashurama, an avatara of Vishnu. Later, sage Vasishta performed a great Yagya or fire-sacrifice, to seek from the gods a provision for the defense of righteousness on earth. In answer to his prayer, one or more youths arose from the very flames of the sacrificial fire, according to different versions of the legend.
Sometime during 16-17th century, the legend came to be applied to the Parihars (Pratihaar), Chauhans (Chahamanas), Solankis (Chalukyas), and Paramaras (Parmars) clans. The Parihar at Kannauj, Chauhans at Ajmer in central Rajasthan, the Solankis in Gujarat, and the Paramaras at Mount Abu.
Evolution of the legend
A large number of inscriptions and texts have come to light since the mid-19th century that allow us to trace the evolution of this legend in detail.
The Agnikunda story is first found in the Nava-sahasanka-charita by Padmagupta, a fictional romance where the hero is identifiable as Sindhuraja, the patron of the author Padmagupta. This work mentions that the progenitor of the Paramaras was created from fire by sage Vashishtha. During the period of decline of the Paramaras of Dhar, the story finds mention in several royal inscriptions. Later, the story is expanded to include two or three other Rajput clans. Eventually, some scholars proposed that all of the Rajputs were created from the Agnikunda.
Suryavanshi rajputs trace their lineage to the Vedic Sun - Surya. Lord Rama was also born in this lineage. Suryavanshi rajputs ruled over Mewar, Marwar, Amber, etc.
Somvanshi/Chandravanshi rajputs descended from Som (the vedic deity Soma or Moon). Chandravanshi and Yaduvanshi are from the same line which bifurcated at King Yadu when his father banished him from becoming the king. Gujarat, Jaisalmer was ruled by Chandravanshi rajputs. The Yaduvanshi trace there lineage to Lord Krishn.
Agnivanshi rajputs have a mythological belief that they originated from fire. Bundi, Kotah, Jalore, Sirohi, Delhi were ruled by Agnivanshi rajputs. In reality Agnivanshi rajputs are also a sub-division of Suryavanshi and Chandravanshi rajputs.
Each vansha is divided into many cula and each cula is further divided into many shakha.
Suryavanshi Rajput kula, Rathore, is divided into these shakha: Dhandhul, Bhadail, Khokra, Jodha etc; Similarly Guhilote cula is subdivided into these shakha: Aharya (at Doongarpur), Sisodiya (at Mewar), Peeparra (at Marwar), etc.
Each shakha has its Gotra Acharya, a genealogical creed, describing the essential peculiarities, religious tenets and pristine locale of the clan. It is a touchstone of affinities and guardian of the laws of intermarriage.

These twelve of 36 clans of rajputs further subdivide:
Gehlote, Parmara, Chauhan, Solanki, Rathore, Tanwar/ Tomar/ Tuar, BirGoojur, Parihaar,chib Jhala, Yadu, Katchwaha, Gor.
Rest of the 24 clans are 'Eka' and do not divide further:
Sengar, Balla, Khurwur, Chawura, Dahima, Dahiya, Byce, Gherwal, Nikumpa, Dewut, Johya, Sikerwal, Dabia, Doda, Mori, Mokarra, Abhirra, Kalchoruk, Agnipala, Aswariya, Hool, Manutwal, Mallia and Chhahil, .
