This is where there is a lad in the 1901 Ireland census who looks like he could be my Grandad, James Hart, aged 7. I have had a look on google maps to see if I can find the road, but to no avail. The North Dock area is highlighted but the street is not there. In fact I cannot find any road in present day Dublin called Tyrone Street - with or without the 'Upper'. Is anyone able to help, please? Many thanks.
