The center of the CELIS family is Saipan, but there is a small branch on Guam.
It all began with a man named AGATÓN CELIS from the Philippines. Records are not consistent in telling us where in the Philippines he was from. Some records say he was from Malate, a district of Manila. Other records say he was from Camarines Norte, a province in the Bicol region. It's possible he was born in Camarines Norte then later moved to Malate, Manila.
Agatón was a soldier under the Spaniards in the Philippines but, in 1843, he was found guilty of some crime, it seems likely a military rebellion, and exiled to Guam. He was on good terms with Governor Santa María of Guam, who employed him in the Government in Hagåtña. It seems he was engaged in clerical work, as he talks about using his pen.
Later he was assigned to Tinian, when that island only had a temporary community of a dozen men who did some animal husbandry for the Guam market, the income being spent on the care of lepers.
Then he was assigned to Saipan as a teacher for the Carolinians, and assisted in teaching what they needed to know to become Catholics. In 1856, he petitioned to have his case pardoned and to receive a salary for his teaching. It was a petition supported by the Chamorro mayor of Saipan and the Spanish priest of Saipan, as well as the Spanish Governor of the Marianas based on Guam.
While in Saipan he married a Carolinian woman in 1857 by the name of Enriqueta Antonia (Aurora). Records about her origins are also not consistent, some saying Eauripik and others saying Lamotrek. Her Christian names are also not always consistent. Sometimes Aurora is added to her names. She would have also had a Carolinian name from birth. Lasiguerag is mentioned as her Carolinian personal name.
Agatón was such an early settler in Saipan that a stream, spring and valley in the Tanapag area are called Sadog As Agatón, Bo'bo' As Agatón and Kannat As Agatón respectively. Sometimes people skip saying the "As."
It's possible that these areas were named after Agatón Celis because he owned land here.
The As Agaton area just south of Tanapag was used as a village or camp for Samoans exiled by the Germans to Saipan in 1909 until the Japanese sent them back to Samoa.
Agatón and Enriqueta had at least these three children that I know of :
IGNACIA, born in Saipan in 1858. She had a son Felipe, born in 1892 with no father stated in his birth record. Felipe married Ana Díaz Castro, daughter of Rodrigo and Luciana. Ana was born in Guam but moved with her parents to Saipan as a child. From them came Celis descendants.
Ignacia had a daughter María who had children out of wedlock, some of whom carried forward the Celis surname.
CARMEN, born in Saipan in 1860, married Simeón Muña Camacho, son of Juan Camacho and Francisca Muña, two of the earliest settlers of Saipan from Guam.
JUAN, born in Saipan in 1865, married María Garrido Iriarte of Guam. It seems Juan lived on Guam at times because a son, José Iriarte Celis, seems to have been born in Guam sometime in the late 1880s. Another son, Joaquín, seems to have been born on Guam around 1891. Joaquín never married. Neither Juan, nor his sons José and Joaquín, appear in the 1897 Guam Census, leading me to believe that they moved back to Saipan, perhaps because María had died, since Juan married (again) in 1896 in Saipan with a Carolinian woman named Nicolasa Huarong. No children seem to have come from this second marriage.
José and Joaquín reappear in the Guam records after 1900 so they must have left Saipan for Guam and settled on Guam for good, with José eventually marrying Nieves Namauleg Tuncap, the daughter of Jaun de Ocampo Tuncap, a Filipino, and Escolástica Angoco Namauleg from Aniguak. Their descendants spell the name CELES, but in the past spelling was inconsistent and both Celis and Celes were used across the board. So the Guam family spells it Celes, but they are of the same clan as the Saipan Celis.
A small, village street in Tanapag, Saipan is named after the founder of the Celis family, Agatón Celis.
Sometimes the Celis family is known as familian Agatón, even though there is only one Celis clan in all the Marianas.
