Back in the 70s I had occasion to meet a nun in a poverty order. She said her sirname was Grace. I thought that was cute given she was a nun and asked if she had changed her family name. She laughed and said no. Upon further conversation I determined she was the sister of the WR Grace family. She said she gave up her family fortune to serve the poor. IMO this is the best example of someone following their beliefs by putting their ego down. Probably not going to happen today given our me me me society.
