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