When I was pregnant with DS, I asked my great aunt for a list of girl names from the family (I was told he was a girl!)
Both DH and I loved Myra (believe it or not we didn't know about Hindley!) It became clear quickly this name is off the table.
I think it's sad such a beautiful name is unusable, yet infamous men in history don't have the same stigma (like Ted / Theodore).
Do you think Myra will ever be usable in the future?
