Place & story
Brusna and Aughalustra
Castlemore parish extends into both Costello and Frenchpark baronies. Samuel Lewis’s 1837 account lists the historical parish under County Mayo and names national schools at Brusna and Aughalustra. Lord Dillon gave four acres to endow the Brusna school. Together the two schools taught about 100 boys and 100 girls; a separate pay school had about 50 boys and 30 girls. These figures concern the wider historical parish, rather than pupils counted solely within today’s Roscommon portion of Costello. [2]
