Still today In Nepali society, we ask,

Tero Bau Ko Naam Ke ho? ( What's your father's name? )..Once you tell them your father's name, then they figure out your background in society.  Ramji Ko chora, Ganeshji ko Chora, Vishnu-ji ko Chora

So when people ask you, do you take your mother's name or father's name?

Mostly, people say father's name,  if so, then, that means you are giving less priority to your mother.  Think.!!
