The Irish Roots Project co-ordinates the efforts of Wikitreers who have Irish ancestry and/or would like to improve the profiles of Irish people and the Irish diaspora on Wikitree.
There has been an explosion of free Irish genealogical records in the last few years and there has never been a better time to bust those brick walls and improve the Irish profiles on Wikitree.
If you would like to join the project we would love to have you. Please post an answer below (including your research interests and what you would like to work on) and follow the instructions on the project page.
