This will give you some idea of exactly where this townland is in Co. Cavan.Also, if you haven't already, check the Ellis Island website. They usually give the age of each passenger (approximate age, as sometimes these folks gave different info when they came to the US). Also if you know your ancestor was Catholic, try checking the RC parishes in Co. Cavan for the area you looking in. They may have info, or cemetery records of Bernard's family.
