So are you astonished OP end up looking like ordinary Pinoy or not really?
OP is more of a quadriracial btw not a Mestizo.
@prau123 That's seems reliant on "what if" though & wishful thinking of Filipinos that they are highly mixed when majority aren't really. I am sure the percentage of mixed Filipinos is higher than that Standford study but I also doubt it's near-majority like so many Filipinos make it out to be. There has never been any myth/legend in her family about having 1 foreign ancestor, she would've grabbed it as an opportunity if there was because she's in love with Spanish culture.
I wonder if FilAms base Filipino looks on FilAm community alone because there is far more variety here & when I say that the look of the guy is common, I mean common amongst ether rich, middle class, & poor Filipinos. & if my friend had that 1 Spanish ancestor from 500 years ago, it would be so diluted, it would likely be less than 1% & negligible.
Wasn't there a post here before of Filipinos who look mestizo yet when they got their DNA back, they don't have any caucasoid ancestry & were almost 100% mongoloid, Austronesian primarily?
Several Filipinos could only trace back to their great great grandparents at best. It's remarkable actually that your friend was able to trace back her ancestry as far back as 1565? If it's oral tradition being passed down from one generation to the next, then how reliable is the information as it gets older? Does she have a Family Tree, pictures, photographs, written somewhere? However it's likely that some Filipinos had a single generation of a Spanish Ancestry without knowing that they ever had one. Remember the Filipino population in Manila and other major cities back in those days were small enough where they had contact with Spaniards at a higher rate compared to today. I do agree with you actually that if your friend had a Spanish Ancestry that it would have been diluted to less than 1% by now.
