Common questions

What twin name goes with Felix?

Matched same-sex options: August, Jasper, Arlo, Otto.
For a girl twin: Stella, Willa, Alma, Ruby. They share Felix's general style but each keeps its own sound. All 20 of them match Felix's 2-syllable length.

How closely should twin names match?

Somewhat more, yes. Twins are said together far more often than other siblings, so a shared style and length suit them. Rhyme is the line not to cross: a near-rhyme for Felix loses a lot of points here.

Should Felix's twin have a different first letter?

Twins share a surname and a birthday, so on forms the first initial is often one way to distinguish their records. A twin of Felix whose name also starts with "F" can be harder to distinguish from Felix on some records, so the twin score rewards a different first letter. None of the names on this page start with "F".

Where does the data come from?

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