Saw this somewhere and just loved it, but it’s not showing up as a real name anywhere except on sites with names from mythology.
What do you think of it? Edesia, nickname [name]Edie[/name].
Wow, I really like it. [name]Do[/name] you know how to pronounce it? Something makes me want to say Ee-duh-SEE-a or Eh-duh-SEE-a instead of E-[name]DEE[/name]-see-a.
Eh-dee-jah is how I would pronounce it.
Please tell me what you think-- honestly! I can handle it! 
Honestly…I like it! I would pronounce it like you did. It sounds mysterious and is far enough from other names that it doesn’t look like a misspelling. It looks like a legitimate, rare name. [name]Edie[/name] is cute too!
