Name-history notes are shown only where a reference is recorded; origins and pronunciations can vary.

For a brother: Griffin, Brady, Rhys, Declan.
For a sister: Murphy, Rory, Brianna, Bridget. These share Connor's style and level of familiarity without rhyming or starting with the same letter.
Should a sibling name match Connor?
Only loosely. A brother or sister name should sound like it was chosen by the same parents as Connor, not like half of a pair. That means a shared era or style — Connor reads as celtic and strong, so lean that way — but a different starting sound and ending. All 24 names here share a style label with Connor. Names that rhyme with Connor or also start with "C" get fewer points here.
Does the origin of a sibling name matter next to Connor?
It helps but is not required. Another Irish name (like Connor) gets a small scoring bonus because shared roots read as deliberate — 16 of the names on this page are Irish too, but a strong style match with Connor matters more either way.
How are the sibling scores for Connor worked out?
We compare every name with Connor on style, how well-known it is, and sound. Style counts most; rhyming with Connor, starting with "C" or ending the same way all lower the score. See the how-we-score page for the details.
