Jeremiah O’Donovan Rossa:

JEREMIAH O’Donovan Rossa (1831 to 1915) was born into an Irish-speaking farming family in the Rosscarbery area of West Cork in 1831 — though the precise location remains a matter of dispute to this day.
This area was notorious, indeed proverbial, for the extent of the suffering experienced during the years of the Great Famine — an event through which he lived and which clearly had a decisive influence on his attitude towards a variety of important contemporary issues in Ireland, most notably the questions of land ownership and the government.
