Volume II of "Erin's Sons" covers the same time period as its predecessor and the same geographic area--the provinces of Newfoundland and Labrador, Prince Edward Island, New Brunswick, and Nova Scotia--and it lists an additional 7,000 Irish arrivals in Atlantic Canada before 1853. What is remarkable about this second volume is the rich variety of information derived from hard-to-find sources such as church records of marriages and burials, cemetery records, headstone inscriptions, military description books, newspapers, poor house records, and passenger lists.

Mrs. Lane is a descendant of the author of the "Star Spangled Banner," Francis Scott Key. Her book traces Key's ancestry back to the American immigrant, Philip Key of London, who settled in St. Mary's County, Maryland in 1720, and forward to a number of Key lines in the U.S. of her own era.
