If you have ancestors from the Beara Peninsula, which is shared between Counties Cork and Kerry, you'll want to check out a database launched yesterday on AmericanAncestors.org, the website of the New England Historic Genealogical Society (NEHGS).
After many months' work, volume 1 of Riobard O'Dwyer's remarkable Annals of Beara has been indexed, and browsable images from volumes 2 and 3 included in the new online collection.
You can find out more in this informative blogpost from the NEHGS.
AmericanAncestors.org holds more than one billion records. You'll need a subscription to view this new Irish database but (free) Guest User access is available to a small number of collections. Details here.
