Bonniconlon was located in County Sligo when the Sligo border went as far as one shore of the Moy in Ballina. It is located in Mayo since the border was changed back to the Ox Mountains Windy Gap. The Howley family originated in Bonniconlon and were Catholic land agents, known for building Belleek Castle in Ballina. Though the local population is relatively small, it is a vibrant community which each year organizes the largest agricultural show west of the River Shannon. The Bonniconlon Agricultural Show attracts large numbers of visitors to the area. A recent development of 48 houses and one-off housing between the village and Ballina has boosted population numbers in the village.
