For a boy twin: Dylan, Hudson, Wesley, Weston. These scored highest for a shared feel with Isla and no rhyme. 19 of the 20 names on this page have the same 2-syllable length as Isla.
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 Isla loses a lot of points here.
Should Isla's twin have a different first letter?
School registers, medical forms and camp lists often go by first initial and surname. A twin of Isla whose name also starts with "I" can be harder to distinguish from Isla on some records, so the twin score rewards a different first letter. None of the names on this page start with "I".
Where does the data come from?
Ranks for Isla and each twin name are taken from US Social Security Administration records. How well each name goes with Isla is our own score, explained on the how-we-score page.
