The book Life in Old Parian says the Cebuano family name Suico has Chinese origin, and I'm looking for the original Chinese characters. I'm trying to narrow it down based on the Hokkien pronunciation of common Chinese family names, but it's hard to find what the characters were for sure.
In the Philippines, it was common for Filipino-Chinese to take both parents' family names as the Spanish did so I'm trying to narrow it down to a combination of surnames that look like Sui and Co combined. From the Wikipedia page on Chinese names in the Philippines it looks like 謝(Sia/Saa) and 孫 (Suan) are good candidates for the Sui part and 許 (Co), or 郭 (Guo) for the Co part. There seem to be other candidates like 蕭 which is pronounced as siau/sio in Hokkien which confuses things further.
