José Díaz Wilson
In the 1800s, there was a Wilson family in the Marianas.
James (in Spanish, Santiago) Wilson arrived in Guam around 1826, according to an 1831 document listing the names of foreigners living on the island.
Other records suggest that his full name was Robert James Wilson.
His main occupation, it seems, the whole time he lived on Guam was pilot at the port. This means he directed to shore the boats that would pick up passengers from the larger ships anchoring at Apra.
He seems to have married twice and had nine children, but we're not sure of all of their names, nor of the first wife's name.
But one of the older children seems to have been a María Wilson, born around 1827 and a 70-year-old widow by the time she is listed in the 1897 Census. It is quite possible that she had married a Díaz. In 1897 she is living with two grandchildren.
There seems to have also been a Juana Wilson, deceased by the 1897 Census but the first wife of Francisco Pangelinan, aged 76 years, listed in the 1897 Census.
Juana Wilson and Francisco Pangelinan could be the parents of one José Wilson Pangelinan, born around 1878 who moved to Saipan. He married twice. His first wife was Dolores San Nicolás Sablan and his second wife was María Cabrera San Nicolás. He was better known as Jose'n Obo.
This Juana Wilson, married to a Francisco Pangelinan, might explain why there is also mention of a man named Lorenzo Wilson Pangelinan, He is absent from the 1897 Census but there does appear there a widow named Valeria de la Cruz, who had been married to a Lorenzo Wilson Pangelinan, dead by 1897.
We are more certain about James' children from his second wife, Rufina Palomo Díaz.
One was a daughter named Eduviges, who married Antonio Pangelinan Martínez. Many of their children married into socially prominent families. Antonia married into the Goyo clan (José Flores Pérez); Emilia married the American William Notley; Ana married Carl Bergquist; Josefa married Julián Pérez Sáiz; Joaquín married Rita Anderson Millinchamp; and Ángel married Emilia Roberto Kamminga.
Another daughter, María, married into the Siket family of Castros. Her husband was Ezequiel León Guerrero Castro. From the Chamorro pronunciation of Ezequiel (E - se - kiet) is derived the family nickname Siket.
Thus it seems that James had two daughters named María; one from the first wife and the other from the second wife.
James had one son whose name appears frequently in the old documents. His name was José, and he followed in his father's footsteps and worked as a pilot at the port. In those days, the boat carrying passengers from the ships would land at the pier in Piti, which was part of the village of Tepungan. José was civic head of Tepungan a few years, too.
José married Encarnación de San Nicolás and had some daughters and a son Antonio, but we cannot find descendants from Antonio and so the Wilson name eventually died out on Guam.
