mw13 – you missed my point (i think). Rav Chaim does not say that to every Shira who sees him. he said it to a handful (or more) and you have no idea what the reason he picked those individuals was. Perhaps there was a reason that those women could not afford a less connected or less “rooted” name. If it was ONLY about the name, i’m guessing he would say it to everyone.
unless someone heard that he gave a blanket statement that all Shira’s should pick new names, that is.
