Saitwal is a Digambar Jain community (primarily in Maharashtra, with presence in other regions). There isn’t a single fixed gotra for all Saitwals. Like many Jain communities, Saitwal families use various gotras as a genealogical label, and lists can differ by locality and family. In practice, gotra is a social identifier more than a spiritual criterion in Jain Dharma.
