From 20th Century literature...
"Tandy" is the name given to a little girl in a short story of the same name written by Sherwood Anderson and published in the anthology, *Winesburg, Ohio* in the year 1919.
Tandy is named by an alcoholic -- yet inspiring -- stranger passing by her house one day, who believes he has invented this name to describe a particular quality in women. The stranger explains to Tandy's father what this is:
"I know about her struggles and her defeats. It is because of her defeats that she is to me the lovely one. Out of her defeats has been born a new quality in woman. I have a name for it. I call it
Tandy. I made up the name when I was a true dreamer and before my body became vile. It is the quality of being strong to be loved. It is something men need from women and that they do not get."
The stranger then turns to the little girl and says:
"Be Tandy, little one... Dare to be strong and courageous. That is the road. Venture anything. Be brave enough to dare to be loved. Be something more than man or woman. Be Tandy."
