Matias Betancourt Cuevas(parents were Felix and Maria) married Eusebia Cortes Nunez (parents Manuel and Isabel).The first record of a child's baptism is 1859.
One was a son named Guillermo Betancourt-Cortes
Guillermo Betancourt Cortes married Natalia Soberat-Bencon.He was a carpenter. Natalias's father was names Juan Nepomuseno Soberal.Her mother was names Maria Engracia Bencon
Guillermo and Natalia had several children - one was Guillermo Betancourt-Soberal - his brother was Franciso Betancourt-Soberal (born 1899).Another brother, Jorge was born in 1895.A number of these children moved to California - San Jose area.I think at least 3 sisters went to California.Moncho was another brother. I believe he was the baby.He was a carpenter.
I got some of this info from a man in Puerto Rico who got it from Church records: Catedral San Felipe de Arecibo and Iglesia Nuestra Senora del Carmen Hatillo.
