If your people came from County Cavan, some of these names may be yours.
Cavan sits in the old kingdom of Breifne, a land of drumlins, small lakes and long memories. When the clerks of the Registrar General counted the births of 1890 and sorted them by surname, a very particular set of names rose to the top of the Cavan list.
Reilly led the county by a wide margin, followed by Smith, Brady and Lynch. The card shows a selection of names from that list, many of them tied closely to the old Gaelic families of the county, such as Brady, McGovern and Galligan. Others, such as Clarke and Martin, reflect later arrivals who settled and became part of the county's story.
A surname can tell you where to start looking. If you find yours here, there is a good chance your family lived within a few miles of the same lake or hill for generations.
