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