I incorrectly stated that Herbert was buried in Byron Cemetery, his funeral was in Byron he is buried in the Cody, Wyoming Cemetery. Could possibly be an obituary for him in the Lovell Chronicle (newspaper) Lovell, Wyoming.
I came across the following from the book, History of the Big Horn Basin, by Charles A. Welch, pub 1940, page 104. "One life, that of the son of the Stock Oil Company's toolpusher, Herbert McKay, was claimed by the well, and a great sum of money."
There is a copy of an memorial card of his funeral in the Family History Center in Lovell, Wy.
