In Jain Dharma, there is no single universal Kuldevi, Kuldevta, or Kshetrapal fixed only by “Vadera gotra + Anchal Gaccha + Barmer.” These are usually family- and village-tradition based, not prescribed in Jain scripture for every gotra.

So for your case, the correct answer is:

• Kuldevi: depends on your family line
• Kuldevta: depends on your ancestral tradition
• Kshetrapal: depends on your local derasar/tirth tradition in Barmer or your family’s original village

For Jain truth and practice, the main devotion is always to the Tirthankaras. Kuldevi/Kuldevta/Kshetrapal are respected as family or local protective traditions, not as a universal Jain rule.

To know the exact names for your family, the most reliable way is:

• ask elders in your family
• check old lagna patrika / vahivat / family records
• ask your ancestral Jain temple or samaj
• see what your Barmer-based lineage has followed traditionally

If you want, I can also help you with a Jain-style way to identify your exact family Kuldevi/Kuldevta from records and elders.
