I just checked my records and although your names and the Amery cemetery match my info, i have a passenger list that shows this family coming in to Quebec in 1905. They then crossed into the US in Minnesota and were living there in Byron for the 1910 census. Also I checked Ellis Island and I cannot find them there.
I have not heard the story about a fire back at the farm in Norway before. There is a fairly large gap between the oldest child Gina (1884) and Ingeborg (1891) who is the next child that I am aware of. Could this be when the fire occurred?
