Who is Jon, Really?

"Oh, I'm sorry," Gina apologized. "I'm third-generation, you know. I remember my grandparents speaking Japanese, but my parents never spoke it around the house. The United States is their country now and they didn't want us to grow up with an accent. And you're right, in Japanese, you say Gina with a hard 'g'. But here in the US I get tired of correcting people who pronounce it with a soft 'g'." "What about the name Jon?" Gina continued. "Is it a form of John or Jonas?"
