3-1-0 for me.
My first name, Sandra, was feminine, and I hadn't noticed many women with the name up to that point. Also, it had a nickname that I was comfortable with. I had never had a nickname that I liked with my old name.
My middle name, Louise, is a gender switch on my old middle name, Louis. I was tormented as a child with that name and now I am proud to have it. I had thought about using my mother's name, Lucille, as a tribute to her, but, while I love my mother greatly, I don't think she would have really understood my changes. She passed several years ago.
I kept my last name as I felt no need to change it.
Now, of course, it seems everytime I turn around, I run into another Sandy!
