Is that just a big fat no? I’m usually not a fan of using a boy name for a girl (having grown up with a masculine name myself, I s’pose), but I’m suddenly really digging [name_f]Fia[/name_f]/[name_f]Fiachna[/name_f]…darn it. It’s so very uncommon in the US. I can’t imagine most people would think me strange if I used it on a girl, but nevertheless, I worry.
I’m not a particular fan of the sound, but it could work if you love it. =]
I’m mostly wondering if I should let myself fall in love! Maybe not… 
In the US I would prefer it for a girl. I strongly believe in the theory that names that end in an -a are for girls. This is just my opinion though.
[name_f]Fiachna[/name_f] is a different name but it could grow on me as it is quirky. If I knew a girl name [name_f]Fiachna[/name_f] and I was exposed to it often enough I’m sure I’d view it normally. In the same way I view [name_f]Siobhan[/name_f].
I’ve never heard of this name and I don’t think it’s a very flattering name. Have you considered [name_f]Fiammetta[/name_f]?
[name_f]Fia[/name_f] is a girls name. [name_f]Fiachna[/name_f] is very hard and masculine to me so I’d avoid.
I think [name_f]Fiachna[/name_f] is pretty cool. Perhaps [name_f]Fianna[/name_f]? sounds similar but sounds a bit more feminine and pronounceable.
Fiachra is a masculine name. I think the only reason Nameberry categorizes it in the girl category is because of the [name_f]Fia[/name_f] part.
I prefer [name_f]Fiammetta[/name_f]. It a gorgeous feminine name that has a ton of nicknames including [name_f]Fia[/name_f].
Thanks everyone! I appreciate the opinions! I have got to make a big list and stop making these singular annoying posts, though!
[name_f]Fiammetta[/name_f] is lovely but it just isn’t quite my style. I think you’re all right about [name_f]Fiachna[/name_f], though, now that I’ve had more time to mull it over. I think I’m just desperate for girl names my husband and I can agree on, and he liked “[name_f]Fia[/name_f]”. I didn’t like it standing on its own. Back to square one.
Going to close the thread, whoops.
