Hi Bill,
I'd suggest that what we are talking about here is a diaspora of the keris from its place of origin (Java) through travel and trade to the Philippines .
(see the Thai Kreis thread in the Warung)
It seems pretty likely the keris came to the Philippines with the Malays .
I'd suggest that questions about the keris be asked in the Warung and queries about the Moro kris be posted here (ethno) along with any conclusions drawn from the results of the information from both forums .
Some questions to explore might be the importance of pamor patterns in Moro krisses, and an exploration of the esoteric importance of the Moro version vs the Javanese or Malay .
Here, I think, you may run into trouble with info from the Philippine side .
The Moro people were not much interested in the act of surrender .
Sadly much of this knowledge may have died with the men who were defending their faith and their lands in the 19th and early 20th centuries .
