Here’s the story. Recently someone named shira was expecting and had complications. Her husband sent her name in to R’ Chaim for a bracha, but R’ Chaim said there cannot be bracha in a name like shira – it’s a Zionistic name, and she should switch her name. She changed her name (with a kiddush and e/t), made sure e/o called her by her new name, and about 1/2 months ago had a healthy baby. Later, I’ve heard that R’ Chaim sent out a letter saying that a/o with the name Shira could change it to Sara b/c it’s very similar = same letters… Hope this helps those that need it.
