Esme is the loveliest name, but I also enjoy Elliot!
My personal fav is Cameron, for boy or girl.
Edwin for a boy, Clementine for a girl.

Baby girl names - Scarlett, Sloane, Reese, Margo, Maeve, Audra, Isla, Willa, Lila, Delilah, Emmaline.

Love that you matched the names with Archer. It is something you need to think about.(like Christina's aversion to another name ending in -er)
Having two similar names in a household can be weird. My grandparents are Bill & Belle and my eldest uncle is Bill. Family gatherings (and work at their family business) gets pretty ridiculous.
Oh, I love your pics, especially Esme and Iris!
