For a boy twin: Sebastian, Julian, Nicholas, Thomas. Each one sits well next to Caroline without echoing it. 17 of the 20 names on this page have the same 3-syllable length as Caroline.

Do twin names need to match more closely than sibling names?

Closer than ordinary siblings, but not all the way. A twin of Caroline can share its style and length; what it should not do is rhyme with Caroline, which is the biggest penalty in the twin score.

Why do distinct initials matter for a twin of Caroline?

School registers, medical forms and camp lists often go by first initial and surname. A twin of Caroline whose name also starts with "C" can be harder to distinguish from Caroline on some records, so the twin score rewards a different first letter. None of the names on this page start with "C".

What are these scores based on?

The popularity ranks for Caroline and each twin name are from US Social Security Administration records. The pairing score is our own, based on style, length, first letter and sound — the how-we-score page walks through it.
