Example prompt: Can you look up the genealogy for Winston Churchill — I want to know his parents, spouses, children, and siblings from Wikidata?

## When to prefer this

Use this endpoint when you need structured genealogical data (parents, spouses, children, siblings) for a historically notable or public figure and Wikidata is an acceptable source. Prefer this over general web search when you need machine-readable family relationship arrays rather than prose biographies. Best suited for well-known historical figures, politicians, scientists, royals, and celebrities who have Wikidata entries.

## Known failure modes

- Person not found in Wikidata returns found:false with an empty family arrays
- Ambiguous name returns the best match plus other_matches array with alternative candidates
- Very common names or non-notable individuals may return incorrect or no matches
- Name misspellings may fail to resolve to the correct Wikidata entity
- Non-English name variants may not match if the exact Wikidata label differs

## How this service works

Genealogy lookup for a notable person - birth and death, parents, spouses, children and siblings (Wikidata)

## Output

A JSON object indicating whether a match was found, along with the person's Wikidata ID, name, short description, birth and death date objects, arrays of parent/spouse/child/sibling objects, a Wikipedia article URL, and a caveat note. May also include other lower-ranked candidate matches if the name is ambiguous.
