I can see the appeal, and would enjoy meeting a little [name_f]Aletha[/name_f]. It does make me think [name_f]Aretha[/name_f] more than anything, but that’s not a big deal. That said, I do much prefer [name_f]Alethea[/name_f], [name_f]Althea[/name_f], Althaea & [name_f]Athena[/name_f].
When I clicked, I assumed it was pronounce uh-LAY-tha, which I was definitely intrigued by. But I can’t say that I personally love it with the uh-LEETH-uh pronunciation. I do think it’s perfectly usable, though
