What is the best way to trace a lost relative(father)?
There are several avenues that you can try to follow. You might start by googling your father’s name in your web browser and see if anything turns up. You can also try the Salvation Army (I don’t know if they do their search for free or how extensive of a search they do or what). Have you asked your mother or grandparents about your father? (They might be able to give you clues, regardless of their personal feelings of him or why he is currently not a part of your life.) As was suggested by someone else, you might try the free 14-day free trial of Ancestry.com or LDS.org (the Mormon church’s website), Rootsweb.com or even go to the library (in many of the larger branches that have internet service, you can access Ancestry with your library card) or look up the US Census. If you are trying to trace your family tree for free (assuming that you or your father are in the US or you are searching for LIVING relatives), you might try the free public records sites of Zabasearch.com or PeopleDa
