Where from the Philippines is Castillon family came from?

during the time of the Spaniards, they occupy the siquijor island in the visayas, there they intermarry with the locals, and some brought forth their families, so there are plenty of castillons in the island, and as time progresses they go to other places and married and settled there.....want to know more about the Castillon in the Philippines origin email me. mangulahingband@Yahoo.com
