Christopher Sugrue...Che Guevara was Irish....

Ernesto Guevara was born to Ernesto Guevara Lynch and his wife, Celia de la Serna y Llosa, on June 14, 1928^[1] in Rosario, Argentina, the eldest of five children in an Argentine family of Basque and Irish descent.^[20][21] In accordance with Spanish naming customs, his legal name (Ernesto Guevara) will sometimes appear with "de la Serna" and/or "Lynch" accompanying it.^[22] Referring to Che's "restless" nature, his father declared "the first thing to note is that in my son's veins flowed the blood of the Irish rebels".^[23]

Very early on in life, Ernestito (as he was then called) developed an "affinity for the poor".^[24] Growing up in a family with leftist leanings, Guevara was introduced to a wide spectrum of political perspectives even as a boy.^[25] His father, a staunch supporter of Republicans from the Spanish Civil War, often hosted many veterans from the conflict in the Guevara home.^[26]

Despite suffering crippling bouts of acute asthma that were to afflict him throughout his life, he excelled as an athlete, enjoying swimming, football, golf, and shooting; while also becoming an "untiring" cyclist.^[27][28] He was an avid rugby union player,^[29] and played at fly-half for Club Universitario de Buenos Aires.^[30] His rugby playing earned him the nickname "Fuser"—a contraction of El Furibundo (raging) and his mother's surname, de la Serna—for his aggressive style of play.^[31]
