Among the 1900+ entries on this blog are a few repetitive subjects. One research source is periodically suggested by our readers, a clear sign of its value in Irish genealogy. Here's a repeat posting from 2016: 

Many sources for free digitized books can be found on the Internet, which is exactly why Peter J. Clarke created a system for dividing them into three main categories for Irish research: Irish History, Biography, and Genealogy, each of which is sub-divided further. More than 6000 titles--most over 100 years old and in the public domain--are available to read and/or download FREE.

Clarke has made it much easier to find the publication you seek. It's entirely possible that a branch of your family has already been researched, and details about a surname are available digitally on Clarke's site. Books are added regularly so one should check back often.

Find out more (or doublecheck for new titles) by looking at Clarke's blogspot. Thanks to Donna for this suggestion.
