OttoPetterson/Peterson family Sweden to MT 1890s
Looking for info re Otto Petterson b. 1854 Varmland, Sweden, d. 1917 Potomac, Missoula, MT.He mar Christina Larson, b. 1861 Elfdalen, Sweden, d. 1910 Missoula, MT.Married in Elfdalen 1880.Otto immigrated in abt 1890-92, settled in Missoula Co, proved up land grant, and sent for his family, who arrived in 1893.Children:Christina, Johanna Maria, Emma Lisbet, Margretta.Christina Larson's mother Marta Olson (Larson)also came with her daughter & family.Marta b. 1836 Elfdalen, d. 1922 Missoula.
Children b. in MT Amanda, Hilda, Andrew, and stillborn girl.
I am looking for the records of the family's immigration through Ellis Island website but have found only a possible Marta Larson and a possible Christina Petterson on same ship.Children not listed, so am unsure these are right women.
Does anyone have any ideas?
