Pearl
Greidy is a modern Spanish-influenced diminutive form of Margarita, which ultimately derives from the Greek word margarites. It carries the same classic meaning of a precious pearl found in the sea. While rare in the United States, it is occasionally used within Latin American communities as a creative variant of traditional names like Greta or Gretchen.
