I was named Susan, a shortened version of my paternal grandmother's middle name chosen by my father. I remained Susan until my godmother handed me to the vicar nine months later when I was baptised and named me Susan Margaret. My father was said to be furious. My godmother was called Peggy so she named me after herself! I like the name Susan, but hate Margaret and only used the initial and then only because now I am married I have a very common surname. My birth certificate has a typed letter attached to it adding the middle name.
