Mbh 3.218.1a

“Markandeya continued, ‘Vrishaspati had a wife (called Tara) belonging to the lunar world. By her, he had six sons partaking of the energy of fire, and one daughter. The fire in whose honour oblations of clarified butter are offered at the Paurnamasya and other sacrifices, was a son of Vrishaspati called Sanju; he was of great ascetic merit. At the Chaturmasya (four-monthly) and Aswamedha (horse) sacrifices, animals are offered first in his honour, and this powerful fire is indicated by numerous flames. Sanju’s wife was called Satya, she was of matchless beauty and she sprang from Dharma (righteousness) for the sake of truth. The blazing fire was his son, and he had three daughters of great religious merit. The fire which is honoured with the first oblations at sacrifices is his first son called Bharadwaja. The second son of Sanju is called Bharata in whose honour oblations of clarified butter are offered with the sacrificial ladle (called Sruk) at all the full moon (Paurnamasaya) sacrifices. Beside these, three sons of whom Bharata is the senior, he had a son named Bharata and a daughter called Bharati. The Bharata fire is the son of Prajapati Bharata Agni (fire). And, O ornament of Bharata’s race, because he is greatly honoured, he is also called the great. Vira is Bharadwaja’s wife; she gave birth to Vira. It is said by the Brahmanas that he is worshipped like Soma (with the same hymns) with offerings of clarified butter. He is joined with Soma in the secondary oblation of clarified butter and is also called Rathaprabhu, Rathadhwana and Kumbhareta. He begot a son named Siddhi by his wife Sarayu, and enveloped the sun with his splendour and from being the presiding genius of the fire sacrifice he is ever mentioned in the hymns in praise of fire. And the fire Nischyavana praises the earth only; he never suffers in reputation, splendour and prosperity. The sinless fire Satya blazing with pure flame is his son.
