as i was with my mother in my child hood days my name was given by mother as Simmy Mary (selected by mothers family)in all records. however my father wanted his mothers' name to be more prominent i.e "Mary" and had used that in all records made by him namely my passport and marriage certificate . now i am in employment with a psu and want my name to be same in all records . since my earlier name was given in my marksheets i was forced to give that while joining the psu but now i want my name to be reflected same as in the passport and marriage certificate namely "Mary". what procedure will i have to follow
