Arfgengni

Arfgengni is an Icelandic term that denotes ancestry or lineage. It can refer to the hereditary transmission of traits across generations as well as the historical or genealogical descent of a person or family. In biology, arfgengni describes heredity, the process by which genetic information is passed from parents to offspring. In genealogy and anthropology, it denotes the lineage or line of descent connecting individuals to their ancestors; it can also refer to inherited social or legal status, property, or family names within a cultural context.

The word is formed from arfi- meaning ancestor and gengni or gengi indicating movement or progression through generations; thus, the concept emphasizes descent and continuity.

Arfgengni is used across disciplines. In genetics, researchers discuss arfgengni when explaining how traits and alleles are transmitted; in family history, it is used to describe a person’s arfgengi and the structure of their family tree. In legal or historical settings, arfgengni may relate to inherited rights, titles, or estates and the way they pass down through generations.

In Icelandic culture, arfgengi and ættfræði (genealogy) play a notable role in the study of family history and identity, with emphasis on tracing connections to forebears. Modern methods, including DNA testing and archival records, complement traditional genealogical work to map arfgengi more precisely.
