I am looking for information about my two great great uncles who emigrated from Kolari, Finland to Calumet, MI. I have found their immigration records but can't find any information about them or their descendents after this. The elder borther Juho Nikumaa immigrated in 1905 and the younger followed in 1907 together with a friend named Viktor Pellikka who later returned to Finland.

I would greatly appreciate any information about them or their descendants as well as suggestions on how to go about in order to find this info.

Best regards,
