In Jainism there isn’t a concept of a “kuldevi” (family deity) like in some Hindu traditions. Jains typically focus on the Tirthankaras (the enlightened teachers) and, in some local or sect-specific practices, on dharma devatas or yakshas/yakshinis who are connected to particular Tirthankaras. So, there isn’t a universal or canonical kuldevi for Jain families.

If you’re trying to understand traditions tied to your family, you might:

• Ask your elders or family members what local customs they follow (if any) related to deities or revered figures.
• See which Jain figures are emphasized in your community (e.g., which Tirthankara or dharma deity is most honored in your temple).

If you’d like, I can explain how Jain reverence typically works (Tirthankaras, Arihants, Siddhas, and any sect-specific practices) in simple terms.
