How this list is scored
How this list is scored
Boy names that sit well beside Jack, ranked by the fit engine: names whose popularity moves with Jack's, from the same era, about as common and with shared origins. Rhymes, shared first letters and matching endings count against. Official birth statistics, not forum votes.
Each candidate scores at most about 52 points against the sibling: 22.5 when the two names' popularity curves moved together across regions and decades, up to 13.5 for a similar median birth year, up to 9 for similar popularity, and about 7 for a shared origin. A rhyme costs 27 points and a matching two-letter ending 4.5. Spellings of the sibling's own name and names on the same stem are never suggested. Only one spelling of each name is listed; the others are shown underneath.
Scores use official birth statistics from 40 regions and origins from Wiktionary. How these figures are computed.
