In Jainism there isn’t a formal concept of “gotra” like in some Hindu traditions. Jain spiritual lineage is traced through the succession of teachers and the lineage of monks and Tirthankaras, not through gotras or clan lineages.

If you are asking about a specific community name or surname “Soni” within Jain or non-Jain contexts, that might be a social or regional identifier rather than a religiously sanctioned Jain gotra. For precise, tradition-specific details (Digambar vs. Shwetambar), there isn’t a canonical Jain gotra system to define.

If you’d like, I can help with more precise details about how Jain lineages are understood within Digambar and Shwetambar traditions.
