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