Ooh, you do have some lovely names. However, I'd probably go for Eleanor. Eleanor is a recent addition to my Top 10, after I quickly fell in love with it, It's pretty, traditional, classy and oozes a vintage element to it, but is also refreshing at the same time - it's well known, but at the moment not overly common (or, at the very least, not common where I'm from). It's a name that would age well, and has feminine charm without being too overly girly.
As it's on my list, I'd probably use the combination Eleanor Daphne. However, to choose a middle name using your top 5, I'd go for Eleanor Vivienne.
