Which way should I spell my son's name

Sapphire

Áedán is an Irish name pronounced Eye-den, the english equivalent to the name is Ayden, however in the english language most people will pronounce this name Aid-den. Im kinda stuck because the origin has asterisk and no one really uses them and i don't expect my child to go out of his way everyday to use them even with the possibility he might still have to correct everyone who says it. Please let me know what you think, I'm willing to take feedback or other suggestions (spelling wise)
