Jorgen Aa. Grave - dead of booze?

Please forgive a foreigner if this isn't the right forum for this enquiery - and if the english isn't perfect. But my mother-in-law was brought up with the following story about her grandfather: After having an illegitimate daughter in 1901 he "went to America where he died of booze". I've find him in the norwegian emmigrant list departure date from Kristiania (Oslo), Norway, 20. oct 1905, Jorgen (written with the norwegian letter o with a slash) Aasmundsson Grave, 41 years, heading for Canada on the ship "Montebello" and the agent "Rasch". That's my last knowledge of him. But it could be helpful to know that his older brother, Jens Aasmundsson Grave left Oslo for the third time 23. june 1927 on the ship "Bergensfjord", agent "Henriksen". He is then a canadian citizen and listed as "farmer" (not translated - the list actually sais farmer). Any suggestions on how to solve this nearly 100 years old family mystery will be appreciated. askeroi
