The Falcon surname in which most from the southern US and the Caribbean descend comes from these cities in the regions of Extremadura, Spain and Andalusia, Spain.
In 1508, Diego Falcon, originally from Montehermoso, Extremadura, Spain, left for Gran Canaria shortly after it was conquered by the Spanish. He lived on the island with his wife Maria Dominquez and his daughter Leonor. He was captain of the Spanish military infantry there and royal mayor of Teror, Gran Canaria. Almost all Falcon families which trace back to the Gran Canaria, including Cuba, Florida, Louisiana and Venezuela are descendant from Diego.
Marcos Alonzo Garza Y del Arcon Falcon was born around 1560 in Lepe, Andalusia, Spain. serving the military and married in 1585 to Juana de Treviño from a prominent Mexico City military family. His assignments took the family to Durango and Zacatecas where his duties were supervising the mining of silver and gold. His whole family ended up in Nuevo León in the time period between 1596 and 1603, after completion of his military career. The family of Marcos Alonzo is included in the list of the 12 original founding families of Monterrey, which was founded in 1596. Almost all Falcon families around northern Mexico and Texas stem from this lineage, including Captain Blas María de la Garza Falcón, who was a Spanish Settler of Tamaulipas and South Texas.
