What would my Roman name be

I would probably go by Dimitri if I lived in Rome, for a various number of reasons. I don't even care if there is a Roman name for Ben, because in Spanish my name is Benjamin (pronounced Ben-hamin) and that ain't gonna cut it. Here's why I'll be Dimitri:

1. Name of main character in the Russian side of Call of Duty 5
2. Name of a very funny comedian, Dimitri Martin
3. Name of a Greek butcher that comes to my house 1-2 times a year to slaughter our male lambs, who in turn pays us for them and serves them to us when we go to his restaurant "Acropolis" in little Greece in Baltimore. delicious!
