Cortober (Irish: Corr an Tobair, meaning 'round hill of the spring well')[1] is a village and townland in County Roscommon, Ireland.

Another Rental of Charles Manners St. George Estate, dated 1842, gives a list of some early residents of Cortober townland, including Andersons, Armstrongs, Backhouses and Bournes.

Here and there were schools founded and managed by people who were imbued with that pioneering spirit and generosity of mind which is so much part of the educator, seemingly scholastically brilliant.
