If you mean “Vatsal”, it is usually understood as the Vatsa / Vatsa gotra in family-lineage usage, not as a special Digambar Jain religious category. In Jainism, gotra is generally a social or family identifier, and Digambar Jains do not have one universal, fixed gotra system for all families. ( jainknowledge.com)

So the short answer is:

• Vatsal = likely Vatsa/Vatsa gotra
• It is a family/community lineage name
• It is not a core Digambar doctrinal concept ( jainknowledge.com)

If you want, I can also explain the Jain meaning of gotra in simple terms.
