How family tree matters, What can it do for us?

Family Tree: Know your extended family. Get amazed how big your family is..
It gives you first hand information of you family thru Statstic link.
Know your relatives in different area.In case of crisis it can really help.
You can get information about other yadavs (family friends - area wise, we all have our own circles) incase required (mostly used for Marriages)..
Be one family..
Hope to see your point of view..
