Looking for further info - beginning with cemetery and obit - on Richard E. Robertson whose TX death certificate says that he died 14 Mar 1928 in Boerne and was buried in "City Cemetery #4." Birth was 26 May 1882 Atchison Co., MO. Information was provided by his wife "Elizabeth," although the only time I can find him on the census was 1910 his wife's name is given as "Etta B."
He's not on Find A Grave, and apparently no cemetery of a similar name currently exists.
What newspaper might have an obit?
