Trying to locate, in Center Ridge Cemetery, the unmarked graves of my gr-grandparents, Richard "Berry" JOHNSON, b. 16 Sept. 1848 - d. 21 Jun. 1920 and Elizabeth "Betty" (HOUSTON) JOHNSON, b. 26 Feb. 1857 - d. 25 Dec. 1925. Family members remember the approximate location before the boundaries were expanded but couldn't be sure. There are two other unmarked graves of children beside them. Is there a register for this cemetery somewhere? Is the Methodist Church the custodian? Any help will be appreciated. Thank you. EWS
