Jerald Napoles (Tagalog: [naˈpolɛs]) is a Filipino theater actor and comedian, known for his role as Tolits in the musical stage play Rak of Aegis. He was previously a talent of Triple A Management and worked for GMA Network; he hosted and starred in the defunct weekly variety show Sunday PinaSaya.
My interpretation of Jerald or Gerald stems from the pronunciation of the letters j and g as "h". It would then be pronounced Herald. Since many names have biblical origins the harking of the herald angels in the Christmas carol came to mind. This etymology seems more straightforward than using the name Harold as the source.
