Shortly after the Zinc Works were constructed in 1915 just a short distance away, erosion of the cemetery’s hillside terrain was becoming an issue when the Zinc Works' toxic emissions started killing the vegetation. Deep gullies were being carved in the ground after strong rains. See the photo above.
By 1920, burials became less frequent, and this once promising business was dying like the surrounding grass.
Multiple disinterments occurred to move bodies to other cemeteries like the Monongahela Cemetery, West Newton Cemetery and others. It’s uncertain how many bodies were disinterred. Back in that time, removing loved ones from a cemetery and reburying them elsewhere was more common than one might think, but maybe this was even more common with those buried in the Gilmore Cemetery due to deteriorating conditions because of the Zinc Works.
MYTH: Despite all the old lore, caskets and bones did NOT wash up on Meldon Avenue. While deep gullies were carved into the cemetery after erosion, it’s our understanding after discussing with the Gilmore family that corners of coffins were occasionally exposed after severe rains, but the gullies were always filled in enough to adequately rebury the coffins.
In 1933, the Gilmore Cemetery stopped paying taxes per a 1933 Return of Capital Stock Tax form.
George W. Gilmore died in 1933 and was buried in his family's plot. He was the second to the last burial in the Gilmore Cemetery.
In 1934 on an Internal Revenue Service form, the Gilmore Cemetery stated, "From the time of the organization of this Cemtery Company in 1882 until 1914 this business was active. At this time The Donora Zinc Works of the U.S. Steel Corporation was built. This Plant is directly across the railroad tracks from the Cemetery. The fumes have destroyed all vegetation. Deep gullies have been caused by rains. Burials are only made in this place when the lot owners cannot afford to bury elsewhere."
Fifty-eight years after Charles Gilmore was buried in 1877, the last interred was also a child in 1935, Darle Kissinger, who was a five-year-old boy and a twin.
All told, there are 1,207 documented burials in the cemetery from 1877 to 1935 including people of all ethnic and racial backgrounds. There is no record of the number of burials that occurred prior to 1877 that would include the Ammon and Castner family members, which would bring the total number of burials in excess of 1,207.
