Baby Name Poll

Hello there! My husband & I are expecting our first child (keeping the sex a surprise) and we are in desperate need for help. Due to a long story that I’m fairly certain none of you care about, we can’t really go to either of our families for help with names. We want something that is unique/uncommon, yet not made up and still be able to age well as our child grows up. I’ve done a bit of "creeping" on this site and found some names from some polls that we are liking: Nava, Zabel, and Cleo for a girl & Lavi, Hazael, Alistair/Alastair & Ezekiel for a boy (sorry for "taking" anyones’ names!). What are your thoughts on those and do you have any other suggestions? Thank you so, SO much! --Katar and Harry
