Here is a Census of Rancho De Los Maderas (Rincon) of Huejuquilla, Jalisco, Mexico during the year 1830.

Marcelo Madera is my maternal great great grandfather. He is the father of Benito Madera. Benito Madera is the father of Maria Clemencia Madera - the spouse of my Paternal Great Grandfather Calixto Madera.

On the Census Marcelo Madera is listed at age 62 years in the year 1830. That would make is approximate birth in the year 1768.
