Same era, but close to Chelsea
These names follow Chelsea's curve too, but we left them out above because they share a first letter or an ending with Chelsea. Some parents like that echo; if you do, start here.
How these were chosen
Each suggestion's share of US babies has followed a curve close to Chelsea's since 1880, and its recent number of babies is within about twelve times Chelsea's, so the names are in the same league. Names starting with the same letter as Chelsea or with the same ending are left out, so the names go together without matching. Spellings of Chelsea itself are excluded.
