A Past Friend Genealogist Did Work on Our Corrigans IN Ireland She Says They Were from the Parish of Drumgoon Townland Kilitee County Cavan Names...

Patrick's father supposedly was from Co.Monaghan...but here is the thing...these families do not show up in any place called Killitee or Drumgoon...could she have gotten the place names wrong...or might they all actually be from Monaghan...just cannot find any records that apply the way she wrote things down...she says she went to Ireland at some point for some of this info...am kind of stuck!!!
Thanks
