An accidental death also might have generated other records, including coroners reports, coroners inquests (if the coroner found negligence or intention),and, as you mentioned, cemetery records and newspaper articles. Depending whom Robert worked for, his employer mightve had to fill out paperwork for a work-related accident.
It sounds like your first problem is you dont know where Robert was at the time of his death. Youll need that information to find coroners records, which are kept at city or county coroner offices (they also may have been transferred to the state archives and/or microfilmed by the Family History Library, which has branch Family History Centers around the world).
Finding historical newspaper articles, in most cases, also requires you to know where he lived. You might get lucky and find Robert by searching a database of digitized, indexed newspapers, such as the subscription sites GenealogyBank and World Vital Records (see our news blog for more information on World Vital Records’ newspaper databases). But most newspapers havent been indexed and digitized, so youd need to use a directory such as the Library of Congress Chronicling America to find newspapers covering his area. Then you could see if a library near you has the paper on microfilm, or try to borrow it through interlibrary loan.
Id suggest searching a 1900 US census database to see if you can pin down a location for Robert in that year. Continue your research on his earlier life, which could turn up information on where and when he moved to the United States. You also should examine your research and family papers on his parents, siblings and other relativesinformation on them might give clues to Roberts whereabouts.
It also might help to do a little historical research on electricity-related happenings in 1901, such as cities that were getting electric power. This article, for example, discusses the dangers of electricity between 1901 and 1909.
