The National Archives of Ireland have released the 1911 census. This is a fascinating resource with scanned copies of the original forms filled in by households around Ireland available to download. Personally when I downloaded the form for my grandfathers family I discovered that my great-grandfather was born during the famine. My great-grandparents spoke both Irish and English, something I can not do and neither could their children. They had 10 children 7 of which were still alive at the time of the census, my father remembers that another 2 died young after the census. Those were harsh times in Ireland.
But my family came from outside Dublin, for Dublin people there is even more than just their family history. The website contains lots of information about the city in 1911.
There were, by 1911, 330 trams operating on lines which ran for 60 miles along the city’s roads, drawing the suburbs tightly to the city.
Those trams ran on 17 routes around the city. Today the Luas has 2 routes, covers 15 miles and has 40 trams. Maybe in some ways times were not so bad in 1911...
