In Jainism there is no single universal Kuldevi for the Kothari surname. Kuldevi is a regional and family-specific practice, decided by your gotra, village, and lineage. So for Jains with the surname Kothari in Rajasthan, the Kuldevi can vary from family to family and town to town. Often, families honor a local Shasan Devi (protective goddess) or may revere well-known regional goddesses, but this is not fixed across all Kotharis.
