Via the Irish Family History blog we see that the second tranche of the 1911 census has gone live on the National Archives website. The website now covers Antrim, Down and Kerry as well as Dublin (which was put up early last year). It’s been a while coming but, that criticism aside, is a great resource for researchers.
The census is very easy to use with a simple search engine with Name and Location fields. Alternatively you can browse by location, and view your ancient neighbours and the general area.
