I was named Rochelle.
My Mom liked the name "Shelly", but thought that sounded too informal. Her good friend and next-door neighbor couldn't get her mind around "Shelly" and always said "Shella"-- which became my childhood and family nickname.
When I started school in first grade, Mom said my name was "Rochelle"... and it is. I became Rochelle in school . People remembered my name because it was a little different.
