Supposing the founders of the Ganga dynasty to have come from Central India, and matured their plans at Perur, in Kadapa district, for the acquisition of Kolar and the midland and southern parts of Mysore, they would soon encounter the opposition of the Mahavali or Bana kings, whose western boundary was probably the Palir, which is close to Kolar on the east. We accordingly find Konguni-varna described as consecrated to
conquer the Bana mandala, and as a wild-fire in consuming the stubble of the forest called Bana. From the east the Ganga princes marched to the
west, and are represented as engaged in leading an expedition to the Konkan or western coast, when they came to Mandali, near Shimoga,
where, by the advice of Simhanandi, they established a chaityalaya. Probably there was a considerable Jain element in the population of
Mysore at the time, over whom Simhanandi exerted his influence to gain their acceptance of the Ganga rule., Mysore: a gazetteer compiled for government, Volume 1, Benjamin Lewis Rice, https://archive.org/stream/mysoreagazettee01ricegoog/mysoreagazettee01ricegoog_djvu.txt , http://www.amazon.com/Mysore-Gazetteer-Compiled-Government-Volume/dp/1174563621

Virasimha, who had five sons, Kamarnava, Danarnava, Ciunarnava, Marasimha, and Vajrahasta. The first of these, giving the kingdom to his maternal uncle, set out with his brothers to conquer the earth, and coming to the Mahendra mountain, worshipped Gokarnasvami, and obtained the crest of a bull and the symbols of sovereignty. He and his brothers subdued Baladitya, who had grown sick of war, and took possession of the (three) Kalingas. Giving Ambavadi to the third brother, S6da or Seda to the fourth, and Kantaka to the fifth, Kamarnava, with his capital at Jantavura, ruled over the Kalingas, nominating his brother Danarnava as his successor. After these two, fifteen kings ruled, ending with Vajrahasta V, who married Vinaya-mahadevi of the Vaidumba family.., Epigraphia carnatica - Vol 9 - page 317, B.
