A.B.’s patrilineal line can be traced back to her tenth great-grandfather, Diego de Olivares.
A.B.’s paternal grandfather was Abraham Gonzalez Quintanilla (the son of Eulogio Quintanilla Longoria and Dolores Gonzalez). Abraham was born in Corpus Christi, Texas. Eulogio was a Mexican emigrant, from Matamoros, Tamaulipas, and was the son of Manuel Quintanilla García and Leonarda Longoria Galván. Dolores was the daughter of a Mexican emigrant, Domingo Hernández Garca (later González Garza), of Cadereyta Jiménez, Nuevo León, and of Jacinta Garza, whose own parents were Mexican.
A.B.’s paternal grandmother was Maria Tereza Calderon (the daughter of Humberto M. Calderón Galván and Concepción Vásquez). Maria was born in Edna, Texas, to Mexican parents, from Zaragoza and Cuatro Ciénegas, respectively both in Coahuila. Humberto was the son of Antonio E. Calderón Saucedo and María Hermila Galván de la Fuente.
A.B.’s maternal grandfather was Ralph H[ernandez] Samora (the son of Pedro “Mike” Samora and Eulalia Hernández). Ralph was born in Amarillo, Texas. Eulalia was the daughter of Agustín Hernández and María Eduvigis Ríos Corrales. Pedro’s parents were said to be José Bernardo Samora, whose biological father was German, and Juana Albina Carvajal Archuleta. It is not clear if this is accurate.
A.B.’s maternal grandmother was Carmel Garcia Mestas (the daughter of Primitivo de la Cruz Maestas and Floripa Garcia). Carmel was born in Alamosa, Colorado. Cruz was the son of Antonio Maestas and María Marcelina Cisneros. Floripa was the daughter of Filomeno García and Perfecta.
