Me..I chose it as a small child. I was born and named after a sister of Dad and one of Mom's, neither of whom I cared much about. But even living in the hills with no running water, no electricity, no indoor bathroom, etc, I still dreamed of a big Victorian house in a greener land and told them I lived somewhere else and my name was Patty O'Brian. I refused to answer to anything else till I met school teachers, all of whom were more stubborn than I could be at that age, but family called me Patty or Paddy.
I write under the name of my late sister Ramona, one nice way to always remember my favorite sis.
