From The Epic City: The World on the Streets of Calcutta, by Kushanava Choudhury (Bloomsbury, 2018), Kindle Loc. approx. 1580-1590:
Bengali last names when transliterated into English often have multiple spellings. For instance, my name, Choudhury, can be Chaudhuri, Chowdhury, Chaudhry, and so on. These variations are used by aunts and cousins in my own family. Other Bengali last names even have varying pronunciations. As with Bob and Robert, so too everyone recognises that Banerjee and Bandopadhyay are the same name. Everyone, except the University of Calcutta. Each name has a prescribed university version. If your birth certificate says Choudhury when the university accepts only Chaudhuri, there will be forms you will have to fill out and get attested, clerks you will have to flatter and treat to tea while you wait to be renamed. Like Yahweh, Ellis Island and the slave masters from Roots, not only will the university play name-giver – on your certificate you will become Chaudhuri, of that there is no doubt – but whether they will recognise your life prior to your conversion is a matter left up to the fates themselves.
