My Family Tree

Son of Robert Dyment and Margaret Murray.

Ray was killed in the St. Francis dam disaster in California on March 13,1928. His brother Willis collected the settlement for Ray, so the assumption is that he died without leaving a wife or children.

Roy A. Dyment worked for the Edison Company at the Edison Kemp construction camp. Victim of the St. Francis Dam disaster. The dam was built between 1924 and 1926 under the supervision of William Rolland, chief engineer and general manager of the Los Angeles Department of Water and Power, then called the Bureau of Water Works and Supply. Three minutes before midnight on March 12, 1928, the dam catastrophically failed, and the resulting flood killed more than 450 people. The collapse of the St. Francis Dam is one of the worst American civil engineering failures of the 20th century and remains the second-greatest loss of life in California's history, after the 1906 San Francisco Earthquake and fire. The disaster marked the end of Mulholland's career. Many bodies were never recovered. Some were found as late as the 1970s.
