madelaine and LightForest, that's interesting you're considering it too! I have never met a Zephyr, and the few people I've told have never known anyone named it. So maybe we'll START a trend. I really do like the name! And madelaine, I don't think it's weird for a girl's name either. It seems more like a boy's name to me, but baby name sites show it as either. Or the alternative Zephyra for a girl. LightForest, I hadn't thought about the seasonal aspect of it, but you're right, that makes it even more enticing for a March (maybe April, in my case :)) baby!
cabbit, I really like the name Astrid, and I think my favorite middle name there is Elizabeth. I think I really like the sound of having a vowel after the D in Astrid - helps it roll off the tongue? Along those lines, I might consider Astrid Eleni (sort of like Leilani, but starting with a vowel). Just my thoughts!
JenO, Hanna Leigh is my favorite in the list, and I bet the initials would be fine. I like the idea of naming your boy Drew if you think that's what you'll be calling him anyway. Drew is a great name! (as is Andrew, but I know a LOT of Andrews, so Drew seems more unique)
