Answer

Sorry, I can only provide information that is clearly established within Jain tradition.

Explanation

“Nalvaya” may refer to a specific Jain family surname, gotra, community branch, or regional lineage. Kuldevi traditions often vary by family, region, and ancestral village, so I should not guess the Kuldevi without verified information.

Takeaway

For the most accurate answer, please check with your family elders, your community records, or your ancestral Jain sangh/trust connected with the Nalvaya lineage.
