Ooh, I like them all! Eleanor is lovely (nns Nora or Leni as well as El/Ellie), as is Sophie (BFG fan, so always loved it). Like Eve and Olivia, and Evie/Liv are nice nns. Rose and Rosa also very pretty.
Erm, if reeeeally pushed, probably Eleanor, although we would be unable to use it. But I think I would if I could!
