Those are all great choices. We are also Jewish and considering Jonah, Lev, Liev (Yiddish), Matan, Omri, Noam, Etrog and Lulav. I am just kidding about the last two - that's my DH's bad joke :) Right now, Jonah is our #1, despite the fact that it reminds me of the little boy from Sleepless in Seattle!
I loved the name Asher for years but now all of a sudden it's heading for the top 50, so we dumped that one. I also love the names Avi and Aviv, but I grew up with two of them, so the names are ruined for me (to use) due to the strong connotations. I also have family in Israel, so the following names are out for me, but might work for you: Micah, Aviad, Yoni, Nati, Natan, Eitan, Dan (pronounced DahhN), Shlomi, Guy and Ari. We had briefly considered Zev, but the more common name/spelling in Hebrew is actually Ze'ev. I don't want any pronunciation issues, so we will probably dump Liev for the same reason. And I third (fourth?) the rec of not using Cohen as a first name, not because it's trendy, but because if you or your husband are not in that tribe, it's kind of a misnomer.
Good luck - would love to hear what you end up going with!
Haven't seen Oren added to the list ... It's probably my number one choice should be lucky enough to have a son. I also love Zev, Dov, Avi, Ari, Uzi, Dar, Bram (okay Avram), Ascher & Ezra are both too popular but I love them, Eben, and Elan. I have an awesome Jewish baby name book, but I haven't gone through it since I'm not prego yet! Best of luck.
Anshl is Yiddish for Asher. It's probably NOT going to follow Asher up the charts because almost nobody is using it, but I like it. It's got the pleasant meaning of Asher and a bit of the edge of Axel.
Admittedly I like Asher enough to consider it in any case.
Did like the suggestion of Oren.
Due to pop culture references, I like Ariel but would only use Ari or Aryeh - but for the same reason, I'd use Uziel but not Uzi.
FTR, Yael is a girl's name, both biblically and culturally.
OP, I'm not sure about your background so I don't know exactly what you're looking for in a name, but some of the ones mentioned might be of Hebrew/Biblical origin, but aren't really in use in any Jewish community I know of (which pretty much run the gamut from completely secular to ultra-Orthodox). Anglicizations of uncommon biblical names (like Eben, Jethro, Abel) would probably come across pretty awkwardly, although if you love a name that's not necessarily reason enough to drop it.
I like the suggestion of Oren! I also thought of Yishai, Nadav, Adiel, Azriel, Ilan, Samson/Shimshon.
I love the names Ilan, Lev, Dan and Zev but only have one not mentioned but has been a long time favorite - Simcha. I know a Simcha (he was call Simmy or Sim) and have loved it as a name since I first heard it.
I love the name Simcha! But to me it's all chick - actually this and Shoshana are our number one baby girl names. Yes I know it's a male name, but it's effeminate kinda like Sascha.
Here are my personal favorite Hebrew-origin names (some quite popular, some not at all so):
I am Jewish myself, and do feel that the whole "Cohen as a first name" trend is a bit odd. Wouldn't personally recommend using that name, as there are so many other great ones to choose from.
