Gatchalian family

Hello everyone! I'm trying to rearrange the Gatchalian genealogy.

Our earliest known patriarch is the chieftain of Li-Han (now Malolos, Bulacan, Philippines), Gat Chulian (also Gatchalian, Gatsalian, Gat sa Li-Han/ Lian/ Liang), a kin of the king of Tondo - Lakan Bunao Dula.

Gat Chulian is my seventh great grandfather. One of her daughters is Basilia Gatchalian who married Tomas Tiongson, son of Ti Ong Son sent by the empress dowager of China to survey the economic and political status of the Philippines.
Basilia's siblings were unknown to us, although it was mentioned in our ancestry book that she indeed has siblings. The descendants adopted the whole name composition Gatchulian with variations of Gatchalian and Gatsalian.

If you have knowledge about other Gatchalians, the exact relation of the family with other ancient noble families, and any other historical references mentioning the clan, please feel free to collaborate with our projects: Gatchalian family and The Royal Kinship of the Kingdom of Tondo (Kamag-anakang Maharlika ng Kaharian ng Tondo).
