Gotra in Digambar Jain context means the ancestral lineage of a family, traced back through generations. It is a social-identity label used by some Jain families to denote family origin and to check lineage in makeshift rituals or arranged marriages. Important points:

• It is a cultural practice among many Jain households (both Digambar and Śvetambar to some extent) rather than a religious requirement.
• In Digambar communities, gotra typically reflects one’s paternal lineage and is often used to ensure marrying within a compatible line or to understand family heritage.
• The exact names of gotras and how strictly they’re observed can vary by region and family. There isn’t a single canonical list across all Digambar groups.
• Monastic Jain traditions (the Digambar monks and nuns) do not have a concept of gotra in the way householder families do; gotra is a lay/community practice.

If you want precise, region-specific gotra names or rules for your community, it’s best to ask your local Digambar temple or family elders, as practices can differ.
