Most of the names are brought down in the sefer.
The mechaber says he went through many names with Reb Chaim shlit”a. that Reb Chaim shlit”a said where no good and go in the category with Shira of modern names.
I wish I could provide more info about the sefer but I think I left it by my parents (I brought it there to show my brother when he was making a briss).
Every name besides some Yiddish ones are clearly recorded in this sefer and the mekoross for them are there as well.
If any one is interested in buying this sefer, the sefer is sold in all seforim stores.
