where did the last name thomas originate from
Thomas (surname) Thomas (and Tomas) is a common surname of English and Welsh origin.
Marcus (name) Marcus is a masculine given name of Ancient Roman pre-Christian origin derived either from Etruscan Marce of unknown meaning (possibly from the Etruscan "mar" which means "to harvest"), or referring to the god Mars. Because Mars was identified as the Roman god of War, the name 'Marcus' can by extension be taken to refer to Ares in the Greek pantheon.
