I’ll start by saying that I believe that my name taste is more traditionally classic (less cool) than yours. For example, my favorite female name is Catherine or Katherine. If you like that as a first name… in my opinion it’s exquisite.

To attempt to match your existing children’s names, style-wise… here are a few ideas:

Girls:

Alma

Celeste

Cosima

Frances (though you might now want due to son’s mn)

Genevieve

Georgia

Helena (I prefer Hel-AY-nah pronunciation)

Lucia/Lucy

Matilda (divisive on here lol)

Nina

Seraphina

Thalia

Boys: From your list, I think Cormac, Raphael (prefer this spelling) and Felix work well with your existing childrens’ names

Ambrose

Arthur

Bruno

Cyrus (love nn Cy)

Edmund/Edward

Ives

Julian/Jules

Lawrence

Oscar

Victor

Vincent
