I don’t know any Filipinos that speak Spanish other than ones who live in CA and learned it there for work/etc reasons. Many have Spanish names, others have odd made up sounding names.
A lot of people forget it became a US territory after we took it from the Spanish in 1898 Spanish American War. When I was there - it was there in the 80s/90s it was Tagalog with a lot of English and smattering of Spanish words...many not quite true Spanish. But the Spanish influence through names and religion was still very apparent.
Oh. So many of them do have Spanish surnames. I thought it had been a Spanish colony for long before the US took over. Muh bad.
