President Lasso’s patrilineal ancestry can be traced back to his eighth great-grandfather, Francisco Lasso de la Vega, of Saldaña, Palencia, Spain.

President Lasso’s paternal grandmother was María Luisa Alvarado Mazón (the daughter of Francisco Alvarado y Chica and Petrona Anselma Alegría Mazón Buenaño). Francisco was the son of José Eugenio Salvador Alvarado Illescas and Policarpa Apolinaria Montúfar. Petrona was the daughter of José Lizardo Mazón and María Antonia Buenaño.

President Lasso’s maternal grandfather was Rafael María Mendoza Pinoargote (the son of Tomás Mendoza and Mercedes Pinoargote).

      Include Andalusian, Canary Islander, Cantabrian, and Castilian as parts of his Spanish ancestry. Also, add remote Belgian [Flemish] and Italian. The surname Poggio came from Genoa. Thus, tag Ligurian as well. I haven’t seen Aragonese, Asturian, Basque, Catalan, Extremaduran, Galician, Leonese, and Valencian so far since the source has been set to private.
