I am of Irish decent, last name Riney. I have very dark, almost black hair and so does my husband so we are guessing that’s what our baby will have too.
I wanted a name that either means dark haired or dark or just sounds like it belongs to a dark haired baby.
We don’t know the gender yet so please leave suggestions for both genders!
I don’t want anything too strange.
thank you so much for your help!
I believe this is what [name]Kieran[/name] means (my middle name).
Although I’ve always thought of it as a boy name, I believe (based on an earlier thread this week) that girls are using it too now.
Good luck,
Chels’
Some searching and thinking leads me too the following. I’ve bolded my favorites here. Best wishes!
More for boys…
[name]Donovan[/name], [name]Duncan[/name], [name]Kieran[/name]/[name]Ciaran[/name]/[name]Kiaran[/name], [name]Kerwin[/name]
More uni
[name]Carey[/name]/[name]Cary[/name]/[name]Kerry[/name] (probably on the feminine side)
[name]Sullivan[/name] (probably more on the masculine side)
More for girls
[name]Keira[/name]
If you look to other traditions there are more! There are probably more Irish ones too but that’s what I found after a little looking that was still very “accessible” since that seemed important. Best wishes!

For something really out-of-the-ordinary, what about Dubheasa (pr. “Duvessa”). It means “Dark lady of the waterfall”, which is quite poetic! [name]Bran[/name] (for boys) or Brannagh (for girls) is derived from “raven”, so could suit a child with black hair. Donncha or [name]Donagh[/name] (pr. as “[name]Dun[/name]-ah”) is a boys’ name meaning “brown”, while Dunlaith (“[name]Dunn[/name]-la”) for girls means “brown princess”. Dubhlainn or Doolin means “black sword”. [name]Oran[/name] or [name]Odhran[/name] can mean “dark-haired” or “otter”. [name]Oisin[/name] (for boys - pr. “Ush-een”) and Damhnait (for girls - pr. “Dav-net”) mean “deer” or “fawn”, so could be a way to reference a brunette baby.
www.babynamesofireland.com has a decent list, with meanings and a “listen” function, so you can get an ear for the pronunciation.
Best of luck!
