Can anyone tell me how to get information from this cemetery?? I have two graves I'm interested in...

HETRICK, Elizabeth: Old--b. 8-Jul-1856, d. 24-May-1924

HETRICK, Mary: Old--b. 1876, d. 1970,
w/o Spencer P. Smith

What would be the most likely funeral home that handled these?? Does the cemetery itself carry information??
