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