Answer

Yes, Fagnia can be found as a surname among some Jain families, especially within certain regional Jain communities.

Explanation

In Jain society, surnames are usually connected with:

• Region or village of origin
• Community or caste-group identity
• Family lineage
• Traditional occupation or clan association

So, if a family uses Fagnia as a surname and belongs to the Jain community, then it may be recognized as a Jain family surname in that context.

However, surnames alone do not always prove religious identity. The same surname may sometimes be used by people of different communities or regions.

Takeaway

Fagnia may be a Jain surname, but whether a particular Fagnia family is Jain depends on that family’s tradition, community, and religious practice.
