Question:

Looking up living family. Where do i start ?

I am Norwegian and am travelling to the US next week. I have family there that I would like to see, but they have moved from the address that I have. I have tried international enquiery for phone number and I have tried on a couple of the comercial sites on the internet, but i only find the old address. Can anyone help ?

Best Answer - Chosen by Asker: If I learned that family from overseas, had come here and unable to find me, I would be DEVASTATED.
