There were a lot of Cleopatras so this may be a different, less famous one.

Didn't John die in infancy? How can this gravestone say John died at 73?

according to wikip, the famous one was Cleopatra VII

Different Cleopatra

This is the Cleopatra that was also known as 'Clee'. Different to 'Patty', 'Cleo' or 'Trish'. All of whom were the most beautiful woman in the world in their time :)
