Genealogy is the study of family pedigrees and the descent of families. It involves researching records like birth, marriage, death, census, military, and church records to trace family lineages back through generations. There are many reasons to research a family tree, such as remembering the past, passing on knowledge to future generations, reconnecting with family, and discovering roots. Good places to start include talking to family members, checking family bibles for recorded events, and examining various types of records. Resources for genealogical research include libraries, archives, churches, courthouses, online databases, and genealogy websites.
