To find friends or family you have lost contact with, try one of these methods:
Call directory enquiries and ask for your friend's number in the city where you think your friend might be living. If there is a long list of subscribers by that name, call all of the numbers and explain that you're looking for the John Smith who grew up in, say, Manchester in the 1950s and attended Kelvin High School. Most people will help.
Phone directories, or electoral rolls, both of which are available in libraries, may help you find a lost friend.
College or university administrations will forward a letter to a former student.
Professional bodies, such as the British Medical Association. keep directories of all people currently in practice. Trade unions keep registers, too. If you know your friend's trade, call the union's headquarters.
Contact the Salvation Army's family tracing service.
