This is a truly testosterone driven name, much more so than Hunter or Mason. In 2010 there were only 14 baby boys named Mars. In 2011 it went up to 23 boys. There were also 97 boys named Aries in 2011. By 2015 it only increased to 27 boys given the name.
The names Marcel, Marcella, Marceline, Marcus & that family all mean "of Mars."
