Common questions
What twin name goes with Charlie?
Matched same-sex options: Ellis, Hollis, Marion, Ira.
For a girl twin: Summer, Stella, Lillian, Esther. These scored highest for a shared feel with Charlie and no rhyme. All 20 of them match Charlie's 2-syllable length.
Do twin names need to match more closely 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 Charlie loses a lot of points here.
Why do distinct initials matter for a twin of Charlie?
School registers, medical forms and camp lists often go by first initial and surname. A twin of Charlie whose name also starts with "C" can be harder to distinguish from Charlie 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?
Ranks for Charlie and each twin name are taken from US Social Security Administration records. How well each name goes with Charlie is our own score, explained on the how-we-score page.
