Yeah, have noticed that. http://www.behindthename.com/top/search.php?terms=Isaiah+&popterm=&gender=both It's not exactly 'three to a class' (that'd be top 30 names) just yet, but definetly being used more. Personally I try to avoid Biblical names, not being Christian myself. Some slip though (only as middle names), but those have other personal significance. Would never use a name just because it 'sounded nice' and certainly not because it was trendy. Those names are nice enough but hearing so often they get a bit dull. Aww Jesi, do feel your pain. Though my given name is nowhere as common. Jessica was the most common girls in the mid 80's, it usurped Jennifer. Can you tell I obsess probably far too much over names. Ah well it's fun and we all need a hobby.
I seriously think people put way too much thought into names. I've never had the urge to use a family name or a "name with meaning" not my bag.
I'm pregnant and it told me it's name was Abren (AYE-bren). don't know the gender. Axyn chose Rae for the middle name. Abren Rae. I really like it.
