Do you want to go ahead and use Samuel Rhys for our last DS? That was the combo I liked best from your list! I think a three year age gap between Owen and Sam was a good choice, too...
Is this good?
LN: Wolfe
DH: Rowan Alasdair
DW: Elisabeth Robin
DS: Owen James (7)
DS: Samuel Rhys "Sam" (4)
DD/DS: (nb)
If so, we can progress onto naming the new DD/DS. It seems our style consists of Celtic, English, and traditional names with an earthy, natural quality. So here are some other names that may work well (from past lists on this game).
Here are some boys' names mentioned in previous rounds we both seemed to like...
Dominic
Finn (I love Finn/Fionn as a diminuitive of Fionnan, but I'd be willing to use it as a singular name)
George (I like as mn)
Llewellyn - love
Oliver (too many O's with Owen?)
Pippin (as a nickname. I would want a fullname)
William - love
Girls' names I like that can work with the current set...
Calla
Catherine - I like as mn
Elaine / Elain - mn. Elaine is eh-LINE.
Elanor / Elinor
Elspeth
Eluned - mn
Ghislaine
Leda
Líadan
Louisa
Lydia
Maisie (fn Mairéad?)
Margaret
Rhoda
Tamsin
Tirion - I would love to use this.
Veda
And some other boys' names that could work with the style...
Ardal
Bran
Desmond
Faolan
Gareth - love
Jonathan - Jon
Lysander
Taliesin
So, so potential combos for each gender...
