Hello,
I just notice you list Anthony as a roman name, starting with Anthony and Cleopatra.
However Anthony (as it's "th" shows) is of Greek origin.
Anthon was the son of Hercules, and all his sons made up the clan of Antonides (part of Heraclides). Each descendant of this clan was called Anthonios (son of Anthon).
Plutarch mentions this in his "Life of Anthonios" chapter 4, section 2.
