ireland1838.com has a great old map of Ireland, a product of the Ordance Surveys of the 1830s. You can click on one section to enlarge, then click on one area of that section to enlarge again and scroll around. It shows civil parishes, towns, mills, and churches, as well as roads, lakes, rivers, and mountains. Some of the town names have changed, but you should be able to navigate by comparing to a more modern map. Diane
