Real-world considerations

  • Familiar — #139 in the latest U.S. ranking.
  • Declan's precise literal meaning remains genuinely unknown beyond a likely 'good' prefix. Separately, Saint Declan's traditional 'pre-Patrician' status and his negotiation with Saint Patrick come from a Life written roughly 700 years after he lived, mixing legendary material with what may be genuine tradition -- this history should be understood as traditional rather than independently verified.
