Ramdasia caste in Haryana is under Schedule Cast but I want to know that which religion pertaining Hindu or Sikh or both?

Basicaly Ramdasia Caste belongs to Punjab. They pertain to both Sikh Schedule Castes & Hindu Schedule Castes. Infact they are schedule caste - unlike hardcore hindus & sikhs, they believe and follow blood relation between Sikh Schedule Castes & Hindu Schedule Castes.
