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