There have been a number of important women who have gone by the name Mary
Mary is Miriam in the Hebrew language.
In Japanese, Mary means, "eternal truth".
In 1905, George M. Cohan wrote a song called "Mary"  (http://www.rienzihills.com/SING/mary.htm) which ended:
- For it is Mary, Mary,
- Plain as any name can be
- But with propriety,
- Society will say Marie
- But it was Mary, Mary,
- Long before the fashions came
- And there is something
- There that sounds so fair,
- It's a grand old name
