I love both of them.
Evelyn slightly more than
Eleanor. I think they're classic and timeless, not 'old lady'. I do think that
Eleanor is a bit heavy for a little girl, so either
Nora or
Ellie would work as nn. But I find it (both of them actually) incredibly interesting on a young woman and very refreshing in the sea of Madisons, Mackenzies and Emmas.
My combo for
Evelyn is
Evelyn Georgia and for
Eleanor it's
Thea Eleanor.
And for what it's worth I think they would make a wonderful sibset.
