Gentlemen,
I'm assuming that the keris, if the Cambodian provenance is accurate, is from the Cham people. They live somewhere in the region between what is now modern Cambodia and Vietnam and according to a history lesson a Kelantanese friend gave long ago, were culturally related to the Malays of Pattani and the Malay Peninsula east coast states. They had a similar Hindu -Buddhist culture before the populace became Muslims.
The language is related to Malay and other Austronesian tongues.
However, the Champa kingdom was slowly swallowed by the Viets and what's left of the people today are usually identified as Cambodian Muslims. I'll try and see of I can dig up more on their keris culture.
