It sure would be nice to know where the Aldays in the Philippines came from. It seems that Batangas is where most of the Filipino Aldays are.
I'm an Alday from Guiuan, Eastern Samar in the Philippines. My late father told me that our brand of Aldays also came from Batangas. I have so far met only one non-relative Alday (i.e. not coming from our town and the neighboring one). I sat next to him during the engineering board exams in Manila. He was, of course, from Batangas.
