Common questions

What twin name goes with Arthur?

Matched same-sex options: Isaac, Robert, Edward, Louis.
For a girl twin: Nora, Clara, Frances, Edith. These scored highest for a shared feel with Arthur and no rhyme. 18 of the 20 names on this page have the same 2-syllable length as Arthur.

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 Arthur loses a lot of points here.

Why do distinct initials matter for a twin of Arthur?

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

Where do these rankings come from?

Ranks for Arthur and each twin name are taken from US Social Security Administration records. How well each name goes with Arthur is our own score, explained on the how-we-score page.
