I have a relative that supposedly emigrated from Sweden to Roche Percee. His name in Sweden was Nils Olsson Ahlström and he was born on July 31, 1865. He left Sweden on April 7, 1905 and the destination was Roche Percee.

I coldn't find him in the 1906 census but I don't really understand how the census works...

On the Swedish Emigrant CD, he was registered twice. Once as Nils Olsson Ahlström and once as Nils Olsson. Has anyone come across this person?
