Hello,
I organized a small family reunion in our house a few years back. We were able to trace from the Primary line who is Adriano Viola migrated to San Miguel de Mayumo Bulacan. He had 5 children 1. Pedro; 2. Bartolome; 3. Bernabe; 4. Valentin; 5. Francisca. My grandfather, the architect Carlos A. Santos-Viola is from the line of Francisca Viola. The only daughter of Adriano who wanted the Viola name alive in our line, hence she order to have her last name Viola added to my grandfather's generation.
