I found the 1911 census and Timothy was a commerical traveller. http://www.census.nationalarchives.ie/reels/nai002689118/
I searched the free site www.irishgenealogy.ie for death records for Timothy and Jane but did not locate a record in the Carrick on Shannon or Boyle registration districts.
I also looked for civil marriage records for the children in the Carrick on Shannon registration district and di not find a record.
Did the family stay in Ireland or move to a different area of Ireland?
