The original Panayan settlements continued to grow and later split up into three groups: one of which remained in the original district (Irong-irong), while another settled at the mouth of Aklan River in northern Panay.
An old manuscript Margitas of uncertain date (discovered by the anthropologist H. Otley Beyer)[REF] give interesting details about the laws, government, social customs, and religious beliefs of the early Visayans, who settled Panay within the first half of the 13th century [REF].
