Buckley loved languages, it seems.

"Born in New York City, Buckley spoke Spanish as his first language before learning French and then English as a child.[2]"

"As a boy, Buckley moved with his family to Mexico[11] before moving to Sharon, Connecticut. He began his formal schooling in France, attending first grade in Paris. By the time Buckley was seven, the family had moved to England, where he received his first formal English-language training at a day school in London. Due to the family's varied places of residence, his first and second languages were Spanish and French.[12] As a boy, he developed a love for horses, hunting, music, sailing, and skiing, all of which were reflected in his later writings. He was homeschooled through the eighth grade using the homeschool curriculum developed by the Calvert School in Baltimore.[13] Just before World War II, around the ages of 12 and 13, he attended the Jesuit preparatory school St John's Beaumont in the English village of Old Windsor.

Buckley's father was an oil developer whose wealth was based in Mexico and became influential in Mexican politics during the military dictatorship of Victoriano Huerta, but was expelled when leftist general Álvaro Obregón became president in 1920."
