George Henry Moore was an Irish politician who, in the 1850s, was a co-founder of the Tenant Right League, of the Catholic Defence Association and, as the Member for Mayo in the United Kingdom Parliament, of the Independent Irish Party. Although an advocate of tenant rights, and renowned for his relief efforts during the Great Famine, at the time of his death in 1870 Moore was defending his rights as a landowner against an oath-bound tenant society, the Ribbonmen. He was the father of the novelist George Augustus Moore and of the Fianna Fáil Senator Maurice George Moore.

George Augustus Moore was an Irish novelist, short-story writer, poet, art critic, memoirist and dramatist. Moore came from a Roman Catholic landed family who lived at Moore Hall in Carra, County Mayo. He originally wanted to be a painter, and studied art in Paris during the 1870s. There, he befriended many of the leading French artists and writers of the day.
