Genealogy research no longer simply consists of following your deceased ancestors back in time from generation to generation. Many family historians are now interested in tracing family lines up to the present day in an effort to locate living relatives, often for DNA testing.

Learn research techniques specific to tracing downward in family trees to the present day.
