I'm not a descendant but am researching Baja California genealogy. I have the following information from Baja California records published by Pablo L. Martinez and David PiÃ±era. Some information is also from familysearch.com.
Joaquina Poyerena/Pollerena was born 5 Dec 1877 in Real del Castillo, Baja California Norte, daughter of Inocencio/Jose Inocente Poyerena and Adelina Cosio.
Her sister Angela was born 26 Sep 1884 in Ensenada, Baja California Norte. Other siblings were Reyes, Maclovia, Evarista, Gabriel, Aurelia and Elias.
Inocencio Poyerena was born 1836/1840 at Rancho Los Verdugos, Alta California, son of Juan de JesÃºs Poyerena and Joaquina Sepulveda. He was a resident of Real del Castillo (a mining town) by 1873 when he married Adelina Cosio, 6 August 1873 there. He was a farmer.
Juan de Jesus Poyerena was born 15 April 1792 at the San Diego Presidio, Alta California, son of Pedro Poyerena and Rosalia Ochoa. He married Joaquina Sepulveda 14 July 1824 at Misson San Gabriel, Alta California.
Pedro Poyerena was born in Villa de Sinaloa, Mexico, and was buried 21 July 1818 at Mission San Gabriel. Rosalia Ochoa was born in Loreto, Baja California and was buried 26 January 1849 at Old Plaza Church, Los Angeles.
Joaquina Sepulveda 29 July 1806 at San Gabriel or Los Angeles, daughter of Juan Jose Sepulveda and Mariana Diaz Lorenzana.
Adelina Cosio was born 1857/1861 at San Francisquito, Los Angeles, and died after 27 May 1899. She was daughter of Francisco Cosio and Soledad Warner.
Francisco Cosio came to Santo Tomas, Baja California, from Alta California around 1857. He married Soledad/Rita Warner.
Soledad Warner was daughter of Tomas Warner and Maria de los Reyes Alvarez.
Tomas Warner was born in England about 1807. He died 10 December 1871 at Rancho La Grulla, Baja California Norte. He is supposed to have arrived in Baja California around 1850, but there are several things that are not clear. He became a Mexican citizen, owned Rancho La Calentura, and was Presidente Municipal of the Ensenada area.
As for Romualdo Jose Lucero, I have a Romualdo Lucero son of Jose Lucero and Presentacion Martinez living in Ensenada in 1904. Do you think this is the same Romualdo?
It would be great if you could provide dates and places for the people you mention, it would make it easier to determine the relationships.
I hope this helps!
