I love Everett! It's my second favorite, personally. :) I say it more with two syllables, EV-rhett, but I think it really comes out more like 2 1/2 syllables--ev-[ah]-rhett. I think Ever or Rhett are the most common nns, but I personally love just Ev--I think it's quite edgy and cool, sort of like Trav for Travis or Liv for Olivia or Soph for Sophie/Sophia.
Honestly, I think Alexander, Madelyn, Genevieve, and Everett would be pretty amazing. :)
ETA: Och, right, where I'm from. I don't really feel comfortable posting state or cities or anything (hence Cair Paravel!), but I'm in a Mid-Atlantic state, if that helps. :)
Thanks @ashthedreamer! Everett has really grown on me -- it's definitely in my top 3! :)
I say it with three syllables (ev-uh-rhett), but the syllables are a bit smashed together, so it almost sounds like 2.5 syllables. There's a city I used to live near with this name, and everyone I knew from the city also pronounced it this way. As far as nicknames go, Rhett would be a great one, Ever is another option I've heard before.
