descendant
Let an agent explain the concept of descendant and its kinship terms, relay how descent is reckoned in genealogy, law and genetics from reference sources, describe cultural variations in descent systems, and distinguish descendants from ancestors, collateral relatives and heirs.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

What it is Filled
A person or organism descended from a particular ancestor through any number of generations, including children, grandchildren, great-grandchildren and more distant lines named by repeated great prefixes or by Latin terms such as proneptis for a great-granddaughter, in contrast to ancestors and to collateral relatives; descent is central to kinship, inheritance law, genealogy, genetics and, in biology, to the concept of descent with modification.
Why it exists Filled
Let an agent explain the concept of descendant and its kinship terms, relay how descent is reckoned in genealogy, law and genetics from reference sources, describe cultural variations in descent systems, and distinguish descendants from ancestors, collateral relatives and heirs.
Distinguishing features Filled
- Lineal descent
- Generational naming
- Legal and genetic senses
- Cultural descent systems
What robots and AI may and may not do Filled
Must not
- Reveal unexpected parentage or descent to anyone without the person's consent.
- Publish living people's family details in genealogies without consent.
- Use descent to claim racial or ethnic superiority.
Only with a human decision
- Sharing genetic genealogy results that identify relatives.
May
- Explain descent and kinship terms, including the great prefixes.
- Help a person trace their own family tree from records they are entitled to see.
Moral aspects Filled
- Family and genetic information reveals private facts about relatives who never consented.
- Descent claims can affect inheritance and belonging.
Who is affected
- Living relatives
- Adoptees and donor-conceived people
Owners Filled
Steward
Nobody owns descent; civil registries record births and parentage.

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Vercy registry: vr.tr.descendant
- Wikidata: Q183905 (https://www.wikidata.org/wiki/Q183905)
Direct properties required Filled
- generations per century: about 3-4 count - typical
- genetic share per generation: about one half ratio - on average
Recognition required Filled
- Person descended from an ancestor
- Children, grandchildren, great-grandchildren, great-great-grandchildren and further generations
- Ancestors are the reverse relation; cousins are collateral; heirs are defined by law
- Not a visible object; a kinship relation.
Capabilities and actions required Filled
- explain the concept and terms
- relay genealogical and legal reckoning
- describe descent systems
- distinguish related terms
Hazards and failure modes required Filled
- Confusing descendants with heirs
- Errors in counting generations and prefixes
- Agents giving personal legal advice on inheritance
Standards and interfaces required Filled
- Inheritance and succession laws defining lineal descendants
- Genealogical standards such as GEDCOM
- Citizenship by descent rules
Context of use required Filled
- Not applicable; a kinship concept.
- children and grandchildren
- great-grandchildren and great-great-grandchildren
- more distant descendants named by repeated prefixes
- lineal descendants in law
- genetic descendants and patrilineal or matrilineal lines
- descendants in biological lineages
Sources Filled

- Wikipedia (fr): Descendants - general description of the item
Open questions
- Should kinship terminology and lineal descendant be separate entries?
- How should genealogical sources be linked?
- The registry entry has merged aliases naming specific generational terms; should they be split off?
