“Ghughu” (or similar spellings like Ghughु / Ghughu) is not known as a specifically Jain community surname.

In India, many Jains use local / regional family surnames that are also used by non‑Jains (for example: Shah, Jain, Singhi, Doshi, etc.). So:

• A person with surname “Ghughu” could be Jain or non‑Jain.
• The surname itself does not prove religion; only family background and practice do.

So, “Ghughu” is not recognized as a distinct “Jain surname” in Jain samaj lists, but a Jain family could have this surname depending on their regional and family history.
