Forgot to add this (thanks Bill).  Like other gov sites, it's not especially user friendly.  Maybe one of these other links will get you there.  If you can't click these, they worked for me cut and paste. 

Lynda

open and scroll to bottom:

http://sipb-server-1.mit.edu/geo?location=Chickamauga

two Conf. cemetaries listed, click on one and then scroll down to "show feature location" (slow to load):

http://mapping.usgs.gov:8888/gnis/owa/gnisprod?f_name=&variant=N&f_state=TN&f_cnty=Hamilton&f_type=cemetery&pop1=&pop2=&elev1=&elev2=&cell=&tab=y

Chatt. Valley cem, scroll down to "show feature location"

http://mapping.usgs.gov:8888/gnis/owa/gnisprod?f_name=Chattanooga&variant=N&f_state=GA&f_cnty=&f_type=cemetery&pop1=&pop2=&elev1=&elev2=&cell=&tab=y

in case those didn't open for you (remember these are gov. sites ;-) try these:
