How can i find lost relatives?

Start looking in the area/address you last knew them to be, contact neighbours, school friends, other family ( like grandparents) who may know where they are....write a letter and give it to people addressed to them, they may say they don't know where they are, however if they do they may passon the letter.
Go on the social websites and search, like Facebook, Myspace, refriends reunited Bebo.
Put an advert in the local paper that you are searching for them.
Look at online directories & the electrol roll
