Can anyone direct me to a map of Dublin City from the 1850's and/or 1860's? I am traveling to Dublin for the first time this summer and I have several family addresses from that period that I want to visit. I need to verify that the street names haven't changed since then. >From a birth certificate in 1867 - 11 Upper Mercer Street >From Shaw's directory 1850 - 7 Trinity Street; 19 North Great Georges Street. Thanks. Adriana
