how do i locate a friend, mona rorstard. her father was a diplomat in norwegion embassy in delhi around 1974?

Question

she was just a very good friend who i want to contact just to check on how she is doing

Answer 1

If you know the father's first name, start with that. Otherwise you can check the Indian diplomatic register, or the Norwegian Foreign Office list of its diplomats, for 1974.

Then you need to track him down (or if deceased, try to find his obituary) unless Mona never married and changed her name.

Here are links to the Norway telephone directories: http://www.numberway.com/phone-numbers/9/ Rostard isn't a Norwegian name AFAIK, but Rostad is, and there are 4 listings for Mona Rostads: http://www.kvasir.no/telefonkatalog/searchresult.html?q=rostad%2C+mona&x=59&y=17

Beyond that, it's ordinary skip tracing. Google, Norwegian newspaper archives, credit bureau check, and so on.

Answer 2

Contact Norwegian embassy and ask the where abouts and address of her father.
