Cabucgayan, Biliran

Cabucgayan derived its name from the snail called bukgay. In the Waray-Waray language, to make a singular noun into a plural noun, the article ka is added before the word and the article an after the word. Kabukgayan, therefore, means a place where there are many snails.

This municipality was created on September 29, 1949 when President Elpidio Quirino issued Executive Order no. 271.
