Mulligan & Brady families of Co. Monaghan

Looking for any information concerning Edward Mulligan and his wife Mary Brady ~my third great grandparents. All or part of this family emigrated to Ontario, Canada possibly around 1837. Known children are James b. 1817, Bridget b. 1822, Ann b.1836 and perhaps John b.1812. Marriage records of Bridget indicate the parents were from Co. Monaghan. Parish is difficult to discern due to poor handwriting, but appears to be Killeevan. Thank you!
