Can you help?

I am trying to find several cousins who were born in Scarborough and the surrounding area. Pam and Barbara Cooper (who are now probably married, and have a different surname) lived somewhere in Eastfield. I seem to remember they had a brother too. I also remember John and Peter, who lived somewhere in the Scalby Road area, at least I think they did.
I'd like to find these people again who I haven't met since childhood. I suppose we'll all be in our 50s or 60's by now. If you can help I'd really appreciate it
