“Gugale” surname on its own is not specifically a Jain surname.

• It is mainly a regional / caste-family surname (commonly seen in Maharashtra), and people with this surname can be Hindu, Jain, or from other backgrounds.
• In Jainism, many families use local surnames (like Shah, Mehta, Bora, Firodiya, Gugale, etc.) which may also be used by non‑Jains. So the same surname can belong to both Jains and non‑Jains.

So: Some Gugale families may be Jain, but “Gugale” ≠ automatically Jain. To know for a particular person, you have to see the family’s actual religion and practice, not just the surname.
