Chava must be around 60 now. I heard her in Germany last year, and her voice was still great.
I don't know where exactly you live, but do you think you could ask in bookshop (I know there is Steimatzky in Jerusalem), whether there are any useful (and reliable) name books? Would you do that for me? I could probably order them online, but I'm lost on Steimatzky's website, as I don'T know how to type Hebrew letters on my computer. (I wouldn't know what to type anyway: how do you say "name book" in Hebrew? "sefer shmot"?).
Thanks in advance!
