In the 1897 Census, there are two women, both widows, with the last name Quisalao. They are both from Aniguak. Quisalao is a native Chamorro name, formed by Qui (Ke) like Quichocho and Quitugua. Salao is a word whose meaning is lost to history, unless we unearth something that tells us what it means.
Maria Quisalao had married a Merfalen.
Natalia Quisalao, possibly her sister, had married a Santos.
