The story of Marcellus
Marcellus began as a Roman cognomen — the affectionate diminutive of Marcus — and became strongly associated with the Claudii, one of the patrician families of the Republic. It stayed in use through the Christian centuries, borne by early martyrs and by two men who served as pope, which kept it alive in church calendars long after the Republic was gone. From Latin it settled into the Romance languages in shortened shapes: Marcel in France, Marcello in Italy, Marcelo across Spain and Portugal. The full Latin form traveled to the United States alongside those, and has stayed on the American record without interruption since national name statistics began.
Meaning
Little Marcus — a diminutive of Marcus, the name tied to Mars, Roman god of war
The chain from Marcellus back to Marcus is not in dispute, and Marcus is generally read as belonging to Mars. What nobody can recover is the meaning of the god's own name, which is older than written Latin.

The trade-off
- An unbroken record from Republican Rome to the present, with no period where the name fell out of written use.
- Ready-made short forms — Marc, Marcel — that need no explaining to anyone.
- Close cousins in French, Italian, Spanish and Portuguese, so the name is recognizable well beyond English.
- The spelling follows the familiar Marcus pattern, so most people get it right on the second try even if not the first.
- Common enough to be known, uncommon enough that sharing a classroom with another is unlikely.
- Four syllables is a lot for a first name, and other people will shorten it whether or not the family does. It helps to decide early which short form you actually want.
- Expect the -llus ending to be respelled as Marcellous, Marsellus or Marcelus, and expect Marcus and Marcelo to be substituted by people reading quickly.
- Marsellus Wallace in Pulp Fiction is spelled differently, but the sound is close enough that some adults will make the connection out loud.
- The name sits mainly with adults in their thirties and older right now, which means a child may be the only young one anyone has met — and also that no one will find the name strange.
