http://municipalityofivisan.jimdo.com/Long before the Spanish invasion, this place was a wilderness, surrounded with thick foliage and big tress. The people lived by groups at first, composed of about five or seven families. Later on, these groups founded a village. Due to the geographical situation of the town the chief livelihood of the people were mostly fishing and a little or farming. Whenever people from far villages yearned for fresh fish they always said. “Let us go the place where there is an abundance of “Ibis” (refers to small fish.) They usually come in groups and stayed for weeks, salting and preserving the small fish that they could get. Later on, when the Spaniards came, they thought it wise to give a proper name to the village. The Provincial Governor appointed a committee. This in turn called a meeting of all the prominent men of the village purposely for the selection of an appropriate name for this pueblo. The people together with the Spanish Officials, aware of the fact that the place was famous for “Ibis”, unanimously deemed it right and proper to call it “Ibisan”. Officially however, the Spaniards called it “Ivisan” because of their preference of letter V to B. Modern scholars nevertheless, under the influence of American educators called it “Ivisan” primarily for the sake of euphony and secondary for the reason that in the old roman writing they write the letter “U” as “V” hence.
