Joseph was the eldest son of Pierre and Flavie (Lepage) Desgroseilliers, my maternal great-great-grandparents. He was born on 20 January 1868 in St-Chrysostome, Châteauguay County, Quebec.  An elder sister and eleven younger brothers (including my great-grandfather Albert) and sisters completed the family.

Joseph's death registration (bottom portion) gives the cause of death as “Accidental Automobile hit by train”. A local history book of St-Charles, Ontario where he lived, gives slightly more detail in French: “fut frappé par le train no 1, près de la gare de Warren” [was hit by the train no. 1, near the station of Warren]. 
Joseph’s funeral took place in St-Charles’ parish cemetery on 11 May 1927. His brother Albert and his son-in-law Vital Brisson were present as witnesses. 
He was survived by his wife Azéline (née Lemieux) and their five surviving children, the youngest one being 13-year-old Lionel.
