As a Jain-focused answer: the Jain tradition does not have a canonical system of “gotra” like some Hindu communities. Therefore, there isn’t an official Jain doctrine that assigns a “Tater gotra” for Oswals in the way Hindu gotras are understood.

Oswal is a well-known Jain merchant community, but sub-groupings within Jains are usually described by lineage, family, or temple affiliations rather than a formal gotra. If you’re looking for a precise cultural or family designation within your own community, it’s best to consult your family records or local Jain community elders.

If you’d like, I can share more on Jain notions of lineage and how families identify themselves in Digambar and Shwetambar traditions.
