The best way to find somebody is, I think, through a social networking site like Facebook.
You can also try out this site: http://www.lostfriendsindia.com/ [I have no idea about this site, just found it through Google search]
Well, as Vandana Madam said it is better you direct your efforts through social networking sites viz., Facebook, Twitter etc. However, I can surely say that interested MHS members will help you out in this venture or you may even find your so called sister in this site as member, who knows?
My best wishes.
