The present official name of the barrio is Cansiwang. Cansiwang derived from the name “Siwang” or “Gibing” in the native dialect. This denotes a woman with a harelip. So, it became the nickname of this woman. Her real name could not be traced anymore. Maybe she did not have a Christian name. She might have lived earlier than the coming of the Spanish friars to Guindulman, so she might have felt the difficulties of going downtown through the jungles just to be baptized. Siwang possessed cavans of rice which could not be consumed until the next harvest. She was popular, being a wealthy woman who once lived in a jungle, a sparsely populated place.
Whenever one went to Siwang to ask or barter his produce for some rice and asked by somebody as to where he was going, he would definitely answer, “moadto kos ka Siwang”. This means, “I am going to Siwang’s house”. When asked where he/she came from, the ready answer was “Kang Siwang” which means that he was coming from Siwang’s place. When hunters chased wild pigs they sometimes followed the direction to Siwang’s house. Then the hunters would shout “Tua’s kang Siwang” meaning that some pigs had run to the direction to Siwang’s house. Hence, the name Cansiwang. Later on the expression “Kang Siwang” became Cansiwang. The change was perhaps caused by the corruption of usage from time to time.
Cansiwang is situated at the western part of Guindulman. It is 3 kilometers away from the national highway. Its neighboring barrios are Canhaway, Guinacot, Cabantian, Lobogon, Lombog, and Tabunoc.
