Don't type in the name of the cemetery Just the city and state and you will usually always display the cemetery that you are are looking for as one of the pins on the map. Note: Cemetery names aren't always consistent so it may be hard to filter by cemetery name. Ex. just typing "Evergreen" in the location box and then selecting "Evergreen Park, Il" from the drop down list will take you straight to the cemetery.
