I was told that a long time ago, there were five brothers who were very good soldiers or warriors for the King of France.
Since the god of war is Mars, they called them the five Mars, or in French Cinq-Mars.

My name is Guy Cinq-Mars, i'm from Roberval, Quebec Canada. What I heard about Cinq-Mars was:
They were Cinq Frere (brothers) and their last name was Mars.. so they called them "voici les Cinq-Mars" every time... after a while they decide to change their name for Cinq-Mars.

As noted in a previous answer, the source of the name is geographic, and it's not related to the date ("March 5th"). The ruins of the chateau are in the town of Cinq-Mars-la-Pile in the Loire Valley. Someone with that last name could be a descendant of a noble family from that region, but other people from the region also adopted the surname. (The reason there are ruins rather than a full chateau is that the Marquis de Cinqmars led a failed revolt against Cardinal Richelieu. In addition to losing his life, the tops of the towers of his chateau were lopped off.)
The speculation I've seen is that "Saint Medard" became "Cinq-Mars" due to the fact that people no longer know who Saint Medard was, but that doesn't explain why the town of Saint Medard in the Loire valley would change its name while the town of Saint Medard in Picardie would keep its name.

Cinq-Mars is a descriptive name that became a surname. Marks or 'marches' were units of land in medieval France. A Marquis was a nobleman whose task it was to defend said land for the king. There was a Marquis de Cinq-Mars (see King Louis XIII and Cardinal Richeleau) who was a nobleman in charge of defending five marches of land. His 'real' name was Henri Coiffier de Ruze.
