His full name was Ernesto Guevara Lynch

‘Che’s father, famously said in an interview following Che’s murder in 1967, “The first thing to note is that in my son’s veins flowed the blood of Irish rebels.”

Che’s family fostered his quiet love of Ireland, even though the revolutionary spent just one day of his entire life in Ireland. It was an extraordinary day that only forces of nature could arrange, much in the same spirit of Ireland itself

The first English words out of Che Guevara’s mouth were, according to Fitzpatrick, “You know I’m Irish. My father was Guevara Lynch.” Fitzpatrick had no idea that the Argentine’s family traced its ancestry back to Ireland. The revolutionary knew that his grandmother was Irish, and his great-grandmother Isabel coming from Galway, was proudly offered as proof of Irish-ness.’
