Hi Jason,
Try to find the name of your ancestral village. Putian Shi is big and is made up of several counties, many towns and villages.
Although most Huang lineages in Putian belonged to the Gangzhou branch, some belonged to the other branches.
Try to ask the senior members of your family about any relatives living in Putian and try to look for old letters from relatives in China.
When you get the information, please post it here.
Regards,
Erik Huang
