Santiago Gregorio O'Farrell (14 March 1861 – 15 May 1926) was an Argentine politician and lawyer of Irish descent.
His father, Don Miguel O’Farrell, was a rancher and politician, who became a deputy in the provincial legislature of Buenos Aires.
[1] O'Farrell spent 1873-74 in Colegio del Salvador but in 1875 he moved to the Jesuit-run Immaculate Conception in Santa Fe Province.
[4] In 1893 at the age of 32 he was appointed president of the Catholic Workers' Circles founded the previous year by the Redemptorist priest Federico Grote.
One of the issues he pressed for was a monument to Admiral William Brown, the Irish born hero of Argentine independence.
