In Gwalior there are many Jain communities (Parwar, Golalare, Agrawal‑Jain, Khandelwal, etc.), so exact surnames can change from area to area. But some common Jain surnames starting with S that you are likely to find (or their close relatives) in and around Gwalior are:

• Shah
• Soni / Sonī
• Saraogi / Sarawagi / Sarogi
• Surana
• Suri
• Singhai / Singhal (very typical in MP, incl. Jain families)
• Sanghvi / Sanghavi
• Seth / Sethia / Sethiya
• Solanki
• Surti
• Srimal / Shrimali

Important points:

• Not everyone with these surnames is Jain (some are also Hindu, etc.).
• And not all Jains in Gwalior use these surnames – many have other initials.
