Help, new to Overseas research

[Trippy]

Hello

I was wondering if anybody could help, I have spent quite a while researching my own family tree all based in the UK.  I have always wanted to research my husbands tree, his grandmother was born in India.

Unfortunately the spelling of her name has been seen in a couple of different versions, and nobody actual know for sure the year she was born (although around 1915)

I have played around over the last 12 months, but want to seriously start persuing the mystery lady!!.  In the past I have typed different variants into FIBIS, and family search.org, but nothing has come out.

Anybody got any ideas, where the best place to start?

Regards
Trippy
