Common questions
What twin name goes with Thomas?
Matched same-sex options: William, Robert, Henry, David.
For a girl twin: Emma, Nora, Alice, Charlotte. They share Thomas's general style but each keeps its own sound. 19 of the 20 names on this page have the same 2-syllable length as Thomas.
Should twin names match more than sibling names?
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 Thomas loses a lot of points here.
Should Thomas'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 Thomas whose name also starts with "T" can be harder to distinguish from Thomas on some records, so the twin score rewards a different first letter. None of the names on this page start with "T".
What are these scores based on?
Thomas's rank and the ranks of the twin names above come from US Social Security Administration records; how well each pairs with Thomas on style, length and sound is scored by NamePairings — see the how-we-score page.
