I've heard in the family lore that my great-great uncle, Alexander Cadwalader, died by suicide, but until last night never found anything substantiating that. Then again, I don't think I've looked terribly hard, either. I think I just sort of assumed any death notice for him would be non-existent or might vaguely reference an unexpected passing. In no way did I expect to find a headline stating he killed himself, and that the hypothesis was his fear of commitment in a sanitarium.
The article explains the cause of death and briefly recounts the incident from the perspective of a member of the household staff. The article mentions the county coroner, but states that a formal inquest into Alexander's death was not necessary.
Alexander was 20 years old at the time of his death on August 6, 1918, and was the youngest of the seven sons of Richard McCall Cadwalder (1839-1918) and Christine Williams Biddle Cadwalader (1847-1900) [see This is the Face of Genealogy]
Rest in Peace.
