Castleisland District Heritage is launching a booklet honouring the memory of the originator of the Moonlighting movement of the late 1870s and 1880s.
The secret Moonlighting organisation was founded by Bob Finn in Castleisland in 1879.
This was a movement to help tenant farmers oppose "land-grabbing" and to help achieve Irish independence.
Former Fine Gael minister Jimmy Deenihan will be launching the booklet this evening at the River Island Hotel, Castleisland at 8pm.
This is a sister booklet to A Sketch of Reverend William Casey, which recalls the life of a priest who aided tenants during the 19th century Land War. .
