There are a lot of names I have mispronounced! Here are a few:
Matthias- I always thought it was pronounced Muh-THEE-us, but a friend had a little boy named this and she pronounces it Muh-TEE-us.
Amelie- I used to pronounce this name AM-muh-lee, but then I heard someone say AHM-muh-lee.
Eisley/Aisley- I never know if it's pronounced I-lee or EYES-lee
Imogene- ImoGIN verses
ImoGENE
Declan- I've heard it pronounced Dee-Clan
