How should i go about finding my sister?

[Kiwi]

I found my half sisters on myspace, actually! Try different spellings of her name, and you can also narrow the search down by stating the city she lives in.

It worked well for me, I found one of them and then got in contact with the other two through her.

If nothing shows up on myspace /facebook/google for her name, try her mothers. A lot of older people have a myspace site now too, even if its just to keep track of what their kids are doing.

Good luck!
