Via Google, I found two people, who I assume are Hindus, using "Gilani" as last name.
One guy is named Ravi Gilani.

Other is named Banjamin Gilani. It even says he is of "Iran origin", but I really doubt it.

Benjamin Gilani is a veteran Indian actor, who has worked in India films, TV serials, and plays. Benjamin was born in Dhariwal town of Gurdaspur district in Punjab on 20 November 1946. He has mastered theatre before getting into Indian cinema.
Benjamin is of Iran origin as his name suggests (Gilani). His ancestors had migrated from Gilan (Iran) to Kashmir. Benjamin's grandfather and his brother later settled in Jagraon near Ludhiana.
I think both are probably Kashmiri Pandits using Gilani similar to how some use Bamzai which I posted before.
