I don't have an answer to where these stones belong but I checked the SSDI in Ancestry.com. J. PORBECK 1917-1978 showed a last residence of Little Rock, Pulaski Co AR. Marie BROCK 1901-1985 shows last residence of Shirley, Van Buren Co, AR. I found a listing for Robert ELROD 1905-1948, SSN # 429-13-3779, but no place of residency was shown. I was unable to locate anything on William Porter BROCK or Leo GABLONMKI. This has been posted as a response on Saline County Message Board Good luck, Doris Lindblad
