Currently I am looking into origin myths about different Brahman communities. There are the famous stories in works like the Sahyaadrikha.n.da about the origins of the Chitpavan, Karhade, and Sarasvata Brahmins of Maharashtra and Goa. Are there any origin stories about the Brahman communities in Tamilnad, Andhra and Karnataka? Best, Madhav Deshpande
