Each suggestion's share of US babies has followed a curve close to Monroe's since 1880, and its recent number of babies is within about twelve times Monroe's, so the names are in the same league. Names starting with the same letter as Monroe or with the same ending are left out, so the names go together without matching. Spellings of Monroe itself are excluded.
