Iris (mn Martha or Elizabeth) and Octavia (mn Louise) were high on my list and Jemima would have been too if it was not odd in France.
They are very different though: Iris is "punchy" and Octavia is more feminine.
Between the two I would have chosen Iris because Octavia is a bit of a chavvy name in the US.
Sorry, I am not being helpful here :o (and DD ended up with a different name...)
