I happen to own a sefer called “V’korey Shmoi B’yisroel” where its brought down from Reb Chaim shlit”a that all modern names (and Shira was one of them), are not names at all and that any one with those names needs to ad a name and be called by the new one only.
Okay, so what qualifies as a “modern” name? How do you (or, perhaps, more importantly, how does R. Chaim) define that?
