“Chandaliya” is generally understood as a Jain family/surname name, often seen among Oswal Jain families. In Jain naming tradition, such surnames usually indicate a lineage, clan, or village-based family origin rather than a separate Jain sect. ( jainknowledge.com)

So, in simple terms:

• Jain connection: It is associated with Jain families, especially Oswal Jains. ( jainknowledge.com)
• Origin: Most likely a family lineage or regional surname that developed over time within the Jain community. ( jainknowledge.com)
• Exact historical root: It can vary by the specific family branch, so one Chandaliya family’s origin may differ from another’s. ( jainknowledge.com)

If you mean a specific Chandaliya Jain gotra, village origin, or clan history, that would need family-specific records or community tradition, because the name alone does not fix one single origin. ( jainknowledge.com)
