Kuldevi of kubadiya

Kuldevi (family deity) is not fixed for all Kubadiya families. In Jain tradition, Kuldevi is decided by each gotra, village, and family lineage, so there isn’t a single universal Kuldevi for the Kubadiya surname. Different Kubadiya families may honor different Shasan Devis (protective goddesses) or a local temple deity, and the exact choice can vary by town and derasar. The important point is that the primary devotion remains to the Tirthankaras; Kuldevi is a protective attendant (Shasan Devi) and the specific goddess is family-specific. You will usually find the exact Kuldevi recorded in your family’s old records or inscribed at your ancestral derasar. ( jainknowledge.com)

What you can do to confirm for your Kubadiya lineage:

• Check your family records (vahivat/patrika) or derasar inscriptions for the named Kuldevi.
• Ask elders or the trustees of your ancestral derasar or community group (mandal) for the traditional Kuldevi of your family.
• If you know your gotra and ancestral town, you can often identify the Kuldevi from that lineage’s established list.

If you’d like, tell me your gotra and ancestral town (and whether your community follows Digambar or Shwetambar practice), and I can point to the most likely traditional Kuldevi pattern for that specific lineage.
