what a pain a? so i guess youve now got to go searching at all the death records for all the towns on route along their journey. the record will be somewhere, its a pain cos if it his name was spelled wrong it goes into the wrong index !!! try searching death records using varied spelling of his surname if that doesnt work try searching for deaths of that time along the route, it will mean trawling through a lot of stuff but you might find an odd looking one that might show his wife as informant. or try searching old newspapers along their journey route. it might have been recored. good luck
