Indian anti-caste movements have a history of changing surnames to signify abandoning caste enjoying participation from both upper and lower castes. Those people and their children and grandchildren still exist today with their cultural and religious identity intact (and unfortunately even caste most of the time). A lot of people use their father's name as a surname too. It's not genocidal.
