Coode Belchamp Walter

I am confused, why are there burials in the cemetery of Belchamp Walter for members of the Coode family?

The register entry for Coode Henry Penrose Rushton, 1928 (record 33) records Henry as a retired army major.

Henry Penrose Rushton Coode and Mary Constance are both buried in (burial #33) in Belchamp Walter cemetary. Charles 23 July 1928 and Mary 6 Dec 1946. It looks like that Henry and Mary resided at Belchamp Hall in 1928. The burial plot is not recorded but it is likely to be in the lower numbered plots and Henry and Mary maybe in the same grave.
