http://www.corkcorp.ie/maps/ For maps of Cork city. To locate Gillabbey Terrace use the Streets Index. I don't know which St. Finbar's church you want but go to the Places of Interest link, they are listed there. A Google search for St. Finbarr's Church, Cork city gave many links. Give the streets index time to download, a bit slow. Even though a place may be listed in the streets index it may not show up on the map but you will get an idea of its location in the city. Can't help with the 1911 census, the LDS Family History Library website will at least let you know which 1911 census film Gillabbey Terrace is listed on. Colman Ahern, Berkeley.
