Although genealogy is at its heart the study of long-deceased ancestors, connecting with living relatives has become almost as important to many family historians. Some seek living kin in an effort to track down family photos; others do it to find family history playmates, plan reunions or identify DNA project participants. Whatever the motivation, one of the most addicting aspects of genealogy is the thrill of finding distant cousins, or in some cases, parents, children or siblings. But this "reverse genealogy" (working from the past to the present) has its own special challenges and requires the researcher to be part genealogist and part private investigator. This presentation covers proven techniques for tracing 20th and 21st century friends and relatives from the past to the present.
