What Old World girl names do you love?
I realized that’s my favorite style after posting in the boys’ section. So similarly, for point of reference (but not limited to this), what would you name a sister for Nikolai, Aleksander, and Blaise? Ingrid will always be my “name that got away”.
Just for fun and expanding my girls list (not naming a current child), so no limits
