Would I be setting up my child for a lifetime of misspelling and mispronunciation?
He-meh-nah
There is some Spanish background so that's the reason behind the name.
Other options:
Alba
Lua
Constanza
Luisa
Carlota
Manuela
Loreto
Regina - Even though I don't think it'd be possible to keep the Reh-he-nah pronounciation and it'd always be Reh-Jee-nuh
(There's a longer list but this is just an idea of what our preferences are so far)
