Sorry Paula: Once you are on the site Home page, scroll down a bit and look under the section "Explore Our Products and Data".
"Click" on "Geographic Names". On the new page that comes up, "Query the GNIS Online Data Bases, "Click" on "United States and Territories".
This will take you to a "form" where you type in State or Territory, then a pull-down menu where you can select "Cemeteries", and also type in the County, if you like. When you press "Submit Query", it then presents a listing of those items which you can "click" on for maps and other data.
