Is this your Basilio Madrid? Birth April 15 1894 Mexico Died March 28 1962 Mother's maiden name-Varela This Basilio/Bacilio had an SS#. If this is the gentleman you are researching you should request a copy of his SS# application for additional information.
I found one border crossing recordfor Bacilio Madrid dated 1919/Nogales/Calexico. Bacilio and his family can be found in the 1930 U.S. Census for San Diego, CA and he gives his year of immigration as 1919.
Maria Barron de Madrid-there are 3 border crossing records for her. Two records have photos of her.She was born in Aponeta, Nayarit Mexico. Her mother was Reyes Rodriguez, her sister Angela Barron Quintero. Angela shows up in the 1930 Mexican Census for Aponeta, Mx with her husband and children.
There are numerous digital images of Catholic Church records for Aponeta, Nayarit, Mexico in addition to Civil Registration records. I looked for records for 1892=1894 and did not find anything but it could be because Bacilio did not know his actual year of birth. Or he was not born in Nayarit.
You may already know all this information on Maria Barron but you did not give much information. Hope it helps.
