“Gangirwal / Gangerwal” is not a general Jain surname list, it is basically a family / clan (gotra‑type) name used in some local Jain communities.

A few important points:

1. No fixed Jain-wide list

- Jain scriptures do not prescribe standard surnames for “Gangirwal” Jains. - Surnames always depend on region + community + family (for example: Oswal, Porwal, Khandelwal, etc.).

1. Gangirwal is more like a lineage name

- In many cases “Gangirwal / Gangerwal” itself works as the surname. - Different branches of the same lineage may also use other common Jain surnames from their area (e.g. Shah, Jain, etc.), but this is family-specific, not a rule for all.

1. How to know your exact surname / gotra

Because this is local and traditional, the only reliable way is: - Ask your family elders (dada‑dadi, nana‑nani, chacha, mama, etc.). - Check old lagna‑patrika (marriage cards) or any family “vahi” (account / genealogy books). - Ask at your local Jain sangh / temple, where they may know how “Gangirwal” families in your area write their surnames.

In Jain dharma, your spiritual progress does not depend on surname or gotra; it depends on right faith, right knowledge, and right conduct. Surname and gotra are only social identifiers.
