Here`s the address to a site with an article that lists the Indian Olympic Squad http://www.timesofindia.com/today/27home2.htm. You should be see some punjabi names under the field hockey team and some of the other sports.

I`m not sure but my friend told me that Ranjeet Randhawa from Fresno, California is a National Champion of India, and will be representing India in the Hurdles.
