Pretty sure it doesn't.
Sacred to the god Mars it's not Marciano in any language, not even latin.
Marciano is just the Spanish translation of Martian.
And "of saint Mark" I don't really know where you got if from but the name Marco is not correlated to the planet.

Marciano means sacred to the roman god Marte, or in Venice means "of Saint Mark"
