Yes that's right about the two brothers in Illinois. He was one of 8 and his 4 brothers all went over to the USA and he to Canada. We heard he worked there as a lumberjack.
We also believe he returned to the UK during WW1 and was in the 102 Canadian forestry corps stationed at Mortimer, Berkshire, England. Any record which shows this would be great. I have searched around the internet for these records but haven't found anything yet.
We aren't entirely sure if the death certificate showing Salisbury belongs to the right Harry Barnes. His whereabouts after emigrating to Canada are hazy so again if any record can help us to find out if he was still there later in life would help.
