Are there Catholic guidelines on naming of children?

Catholics in India, for the last few generations, have been following a unique practice of naming their children. The children are invariably given the baptismal name after a saint; but once they enter school, many children are given Indian names which hardly have any resemblance to the baptismal name, and which eventually become their official name. Many of such official names owe their origin to names of natural forces like sun, light, wind etc. and of objects like precious stones , flowers etc. I would like to know whether Catholic Church has issued instructions, at any point of time, on how Catholic couples should name their children on baptism and thereafter.
