Looking for my older brother and younger sister what is the best course of action to find them?

Question

i know my older brothers names and date of birth but i only know my little sisters first name

Answer 1

I think the right course of action would be first of all to put this question into the Genealogy section as I am sure there will be lots of people with good advice for you there. 2nd - there is 192.com here in UK, a phone directory service. There might be one where you live.

Best wishes. UK
