Best Genealogy Websites for Researching Irish Ancestors

Researching your Irish ancestors online can be difficult as there is no one-stop website with vast quantities of Irish family history records. Yet many sites offer valuable data for researching Irish ancestry in the form of extractions, transcriptions and digitized images. The sites presented here offer a mix of free and subscription-based (pay) content, but all represent major sources for online Irish family tree research.
