For some information on Kamboj Yugan de Aarpaar  Punjabi ie The Kambojas Through the Ages See Link    The book was  written in Punjabi language and the references cited in the text are from the most notable scholar community The reviews for the book appeared in The Tribune published Chandigarh and Hindi newspapers published from Jullundur The book really contains a well researched information from ancient Sanskrit and Pali texts It is indeed good work to cite on Kambojas  Also i am removing the irrelevant tag unless some specifically points out theinappropriate or misinterpreted citations  in the article   you do your best to cleanup the article but if you try to delete any relevant information on the Kambojs I will sure restore it back
