The Palomos don't show up in a Guam census until the 1758 census, and under one man - Bernardo Ignacio Palomo, who is listed as a Spanish soldier. Whether he was from Spain, Latin America or the Philippines is unknown. But people with Spanish blood, whether they were "pure" Spaniards from Spain, or either "pure" or mixed blooded from Latin America or the Philippines, would have been listed as "Spaniards."
Bernardo married Maria Teresa Tenorio. There are three Tenorios listed in the 1727 census, all in the Spanish list. One of them married a Chamorro by the last name Taimaktos (meaning "unending") and the other two married a Cardenas and a Benavente. We don't know which of these is Maria Teresa's family.
I wouldn't be surprised if the famous Padre Palomo was the grandson or great-grandson of Bernardo Ignacio, because Padre Palomo's full name was Jose Bernardo.
By 1897, there were three big clans of Palomos :
Silvestre Inocencio Rodriguez Palomo (the father of Padre Palomo)
and his wife Rita Cruz Torres
Juan Rodriguez Palomo
and his wife Florentina de Leon
some of their descendants married into the Sablan family (Sablan-Palomo clan)
Luis Dueñas Palomo
and his wife Dolores Blas
they had many children, especially daughters
Luis Quintanilla Palomo
and his wife Rosa Duenas Palomo (relatives!)
Vicente Quintanilla Palomo
and his wife Ana Ramirez Roberto
two of their daughters married into the Perez (Boñao) family
another daughter, Maria, married Pedro Ada
a son, Jose, was the first Chamorro to obtain a PhD
There were other Palomos in the 1897 census, but I cannot identify yet their inter-connections.
