Wonder if this is his death registration in England?
DEATH: Edmund J. Kellie, age 56, Jan./Mar.1946 Coventry district volume 6d page 980.
Unfortunately, English death certificates don't have nearly as much detail as Scottish ones and the reliability of the details are dependent upon the informant's knowledge. Personal details will be name, age, occupation, status (single, married, divorced) as well as date, place and cause of death.
Will have a look for possible Atlantic travel and post again if I do find any leads.
