Rosario Flores Leon Guerrero was born on March 14, 1920 and died on April 2, 2024 at the age of 104 years 19 days, making him the oldest known person alive in Guam and the 4th oldest person in the country's history
I haven't found the oldest person on Guam currently, does anyone have that information?
