Real-world considerations

  • Spelling note: Killian.
  • Cillian's own root meaning is documented as "uncertain" even before accounting for Kylian being a further French variant of that name, so no confident literal meaning can be assigned to Kylian beyond the church-related Old Irish hypothesis for its root. This profile keeps Kylian (French spelling, strongly associated with footballer Kylian Mbappé) as a distinct identity from the separate Irish spelling Cillian, per this pack's identity-preservation policy.
