A name of an individual is associated with their identity. Hence the importance of given a good name to a new born has been an age-old practise. Though in certain community, the importance to name a new born with that of a divine god or goddess is considered auspicious.
Though this is still in practise, there is another set of community who would believe that the ancestral name should be followed repeatedly. Which means, a new born will get the name of his/her grandparents. Thus, there are varied practises.
Even today, In Indian society, the above practises are in existence. However, with slight modification. Here the importance of name as per the Astrological guide-lines is followed.

Thus, the present generation has followed the tradition of naming their Child as per the earlier practise, followed by their ancestors. But with the only modification of given importance of astrology in it.
