Hi Listers, http://griffiths.askaboutireland.ie/gv4/gv_family_search_form.php I have just discovered that the 1850's Maps in the Griffiths Evaluation are now overlaid onto the Google map base with a transparency slider. Search any location - click on 1850's map then zoom right out. Almost all of Tyrone is now covered with the townland maps - there are a few gaps. Use the transparency slider to view the underlying Google Map. Zoom in on your area of interest and use the slider to reveal the Townland overlay (after a minute or so). Keep zooming to get the full details of occupation. Brilliant!! ---------------------- Barry Graham Melbourne, Australia
