Photographer Volunteer reports that the grave is not listed in the current cemetery listings. That, of course does not mean it isn't there, or that anyone poked a stick around in the old section (died 1917) and attempted to find stones just below the soil.

Since the following obituary specifically indicates this cemetery, I have chose to leave this memorial as is. Please contact me if it is determined he is buried elsewhere or the remains were removed and buried elsewhere. PJD

M. K. Beymer, who died at Dearing last Thursday after a long illness with tuberculosis, was buried Sunday. Among his effects after his death was found his obituary, written by him not long before, for publication in newspapers. This obituary notice is printed substantially as written by him:
"M K. Beymer was born in Indiana in 1874, on August 17. When he was twelve years old he went with his parents to Missouri where he lived until 1896. In that year he was united in marriage to Miss Kate Mondy. Four children blessed this union. The break in the circle was the death of the wife which occurred Aug. 23, 1908. Later he married Miss Delphia Baugh and moved to Dearing Kansas, where death laid claim to the youngest child, Troy Beymer, in 1910. The oldest child died on the 18th day of February, 1917. He joined the Methodist church in the year 1908 and had lived a good Christian for years. He died in the year 1917 in the month of November at the age of 43 years and two months. He leaves a wife and two children, two grandchildren, mother, brothers and sisters and a host of friends to mourn his death."
The funeral was held at the Dearing U. B. church Sunday at 2 p.m. by Rev. Tinnell, of Coffeyville, in the presence of a host of friends who had come to pay their last respects. And the remains were tenderly laid to rest in the Robbins cemetery, there to await the judgment day. Peace to his spirit.
