Genealogy (from Greek: γενεαλογία genealogia from γενεά genea, "generation" and λόγος logos, "knowledge") is the study of families, family history, and the tracing of their lineages. Genealogists use oral interviews, historical records, genetic analysis, and other records to obtain information about a family and to demonstrate kinship and pedigrees of its members. The results are often displayed in charts or written as narratives. Although generally used interchangeably, strictly speaking, "genealogy" begins with a person who is usually deceased and traces his or her descendants forward in time, whereas, "family history" begins with a person who is usually living and traces his or her ancestors. The pursuit of family history and origins tends to be shaped by several motives, including the desire to carve out a place for one's family in the larger historical picture, a sense of responsibility to preserve the past for future generations, and self-satisfaction in accurate storytelling.
