Answer

If you mean Nagarparkar / Tharparkar (Sindh), I could not verify any specific 12th-century Jain names from the reliable sources I found. The records I found confirm that this area had a strong Jain presence, with Jain temples and ruins, and that Pari Nagar was once a flourishing town before being destroyed in the 12th century. ( irrigation.sindh.gov.pk)

Explanation

The sources describe Jain temples at Bhodesar, Gori, and Virawah, and mention that the region was once prosperous for Jains. However, they do not clearly preserve the personal names of prominent Jains from the 12th century in Parkar. So I would not want to guess and give you an uncertain name. ( thefridaytimes.com)

Spiritual Understanding

In Jain history, many sacred places are remembered more through their temples, inscriptions, and community memory than through surviving personal records. That is why some regions are historically important for Jain Dharma even when individual names are lost over time. ( thefridaytimes.com)

Takeaway

So, the honest answer is: I cannot confidently name prominent 12th-century Jains of Parkar from the sources I found. I can only confirm the region’s strong Jain heritage.
