# Fairchildren
**Domain:** Corporate Lineage / Silicon Valley
**Doc Type:** Canonical Lineage Node
**Maturity:** Developed
## Definition
**Fairchildren** is the informal name for companies founded by Fairchild Semiconductor alumni or descended through subsequent spin-offs.
## Nexus Context
The Computer History Museum documents a branching genealogy extending across multiple technology eras. [[articles/The Evolutionary Roots of Silicon Valley|The Evolutionary Roots of Silicon Valley]] uses this as more than metaphor: people carry skills, practices, networks and capital across organizational boundaries, producing traceable descent with modification.
## Continuity Context
Corporate lineage clarifies [[wiki/Descent vs Derivation|Descent vs Derivation]]. A descendant company may inherit personnel and technology without being the same legal or moral person as its ancestor. Provenance can transmit capability and obligation, but identity requires separate criteria.
## Key Insight
**Institutional inheritance can be real and causally powerful without making descendants identical to their source.**
