Same era, but close to Finn
These names follow Finn's curve too, but we left them out above because they share a first letter or an ending with Finn. 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 Finn's since 1880, and its recent number of babies is within about twelve times Finn's, so the names are in the same league. Names starting with the same letter as Finn or with the same ending are left out, so the names go together without matching. Spellings of Finn itself are excluded.
