Can you identify the first Chamorro name to ever be printed on US currency? If you guessed Villagomez, you guessed wrong. If you guessed Gumataotao, then you probably know that Rosie Gumataotao Rios is our current Treasurer. Rosie isn't Chamorro, but her husband Jose Diaz Gumataotao is a Chamorro from Guam. Feel free to use this factoid at your next beach bbq.
