The website Topotijdreis [Topo Time Travel] allows you to view old topographical maps from 1815 to 2015 of the area where your ancestors lived. Not quite the same as an actual time machine, but it will have to do!
You can zoom in on the map or search for places in the top right corner. Different zoom levels have different maps, so be sure to zoom in and out. The slider on the left allows you to select the year that you want to see a map for. You can also hit the play button in the top left corner to see how the landscape changed over time.
