I have two absolute favourites for girls:
Agnes Jane Elizabeth (Elizabeth is my mother's name)
Maude Isabella Louise
but, I don't know what other girls names fit into their style nicely. I love Clara but that seems too modern and light, and Virginia is lovely, but, not sure it's appropriate, and, it's the name of one of my 3 aunties. I know for a 3rd girls name, the middles would be Johannah Grace, but I have no idea for a first name. The following are out as FN options:
Gladys
Beulah
Doris
Gertrude
Eudora
Eunice
Harriet
Thank you
Also, I'm sure on what order the middle names should be;
Agnes Jane Elizabeth or Agnes Elizabeth Jane
Maude Isabella Louise or Maude Louise Isabella
