He died suddenly while waiting for a street car to pick him up at Weston, W.VA. after his day's labor. The attending physician pronounced his death due to being gassed in World War 1, in France. He was buried in the Greenlawn Cemetary at Clarksburg, W.Va.
The basic source for both pieces is Stephen Post Queen. It's not clear when he wrote the Queen Family Book that is cited throughout the Angelfire site.
