i think if you like it you should use it. i have 2 cousins who both have 'charlie's' one is a boy and one is a girl.. and they do see each other often! (i think one cousin stole the name off the other who had told everyone 'thats what i'm going to name.' before her bub was born, but she decide to still use it anyway. iykwim?)
that didnt really make sense... but i hope you get my drift
I would still use it if you cant find any other name that you love just as much.
Perhaps you can spell it Lia - like Mia.
There is always the option of having Leah as a middle name if you happen to find another girls name that you both like.
I think it is too similar, but if you love it I would go for it.
I have a cousin who has a son named Cale, and I absolutely loved the name Caleb... but because of our grandparents, we decided not to use Caleb as it would get way too confusing for the grandparents.
I think you can use it! My friend's 2 neice are Mia and Eliah and they live together!!! Also I have a cousin that I don't know that has a daughter with the same name as my daughter, not a both cuz I NEVER see them.
