Common questions

What twin name goes with Peter?

Matched same-sex options: Stephen, Leon, Steven, Eugene.
For a girl twin: Thea, Cleo, Georgia, Daphne. They share Peter's general style but each keeps its own sound. All 20 of them match Peter's 2-syllable length.

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

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

Why do distinct initials matter for a twin of Peter?

A lot of paperwork, from class lists to doctor's files, shows only a first initial and a surname. A twin of Peter whose name also starts with "P" can be harder to distinguish from Peter on some records, so the twin score rewards a different first letter. None of the names on this page start with "P".

What are these scores based on?

Peter's rank and the ranks of the twin names above come from US Social Security Administration records; how well each pairs with Peter on style, length and sound is scored by NamePairings — see the how-we-score page.
