This comes from a follower to this blog, Elizabet: 

What about 7 Marys?

1. MIRIAM*, sister of Moses, (whose name would be Hellenized as “Mariam”, and Anglicanized as “Mary”). *(I realize there’s another Miriam mentioned in 1 Chronicles 4:17, but we don’t know much about her.)
2. Mary Mother of Jesus
3. Mary Wife of Cleopas & Mother of James the Less
4. Mary Magdalene
5. Mary of Bethany
6. Mary Mother of John Mark
7. Mary of Romans 16:6 

Thanks, Elizabet!
