Descriptive list of the archive collection of Daniel MacCarthy Glas (1807 - 1884) which is preserved by Cork City and County Archives Service. The Daniel MacCarthy (Glas) Collection comprises almost 1,400 unique items, containing personal letters, manuscripts, photographs, paintings, and drawings. As with any large personal or family archive, the scope of the collection is immense, documenting a range of topics: from the lineage of the MacCarthy clan, to 19th-century poetry and historiography, the Irish nationalist movement, the history of Early Modern Ireland, the French Revolution of 1848, the British Empire in India and South Africa, and the Great Famine in Ireland. Most of the material in the collection relates to Daniel's historical research into the life of Florence (Finian, Finghín) MacCarthy Reagh (c.1562–c.1640), Gaelic chieftain and scholar, and the MacCarthy clan.
