What is significant about Phoenix’s name?

Named after both the mythological bird that rises renewed from the ashes of a fire, and the city in which author Eudora Welty was born and died, the elderly black grandmother using a cane made from umbrella to maintain her balance while walking in unlaced shoes may seem far removed from the heroes of legend. Yet while Phoenix Jackson may move slowly, she proves that she is a force to be reckoned with due to her dogged perseverance along the path to her grandson's medicine.
