In a past posting I described how I located the homestead of my great-grandparents Albert and Mary Pohl near Turtle Creek, Pennsylvania. I’ve since found that Google Earth is another tool to further visualize the location. It is helpful in modernizing old maps to better understand where my ancestors lived.
What I did is add an overlay of an old map to the modern world shown in Google Earth. This allows you to see precisely where a road, building or property once stood in relation to what’s there now.
