A few more...
Quoting Mrs. God of Thunder:" A few more... Poe Charlotte Poe Elizabeth Poe Christine"
I like Poe Charlotte as well and i think Poe Christine sounds great together!
If you are dead set on using Poe and it has alot of meaning to you personally, then i say use it... But i hope you consider using it as a mn.. While it may have meaning to you, your daughter is going to be the one who has to live with the name.
Baby names?! Are you pregnant?! :D
