I think it's does not matter from where Thackery migrant but interestingly to know the answer from the Raj about the new serach and as he is always saying and using the word migrant. if still our hostory say "Arayan " is the migrant who came to Bharat many senturies than raj grandfather came to mumbai only 20 year before in search of Jobs.
Now Raj is Liable to let people know about his opinion becuase it is the people to whome he is playing politics.
