Google Maps provides you with the ability to create your own maps. I am finding this function useful for genealogy.
Google Maps Morris County, New Jersey
In the map above, I marked burial places for various families in Morris County, New Jersey. This helps me visualize their geographical proximity. I can add locations of residences and places of worship to establish a clearer picture of the close interactions among these people. Some of the sites are not public cemeteries and finding them is difficult. I shared this map with other researchers to enable them to find the private burial grounds.
The map could also be used to help you plan a trip to a distant location. You could include cemeteries, churches, homesteads, as well as local repositories.
