Supposedly they came to America with their son Frederick from Germany in 1854. Lived two years in Illinois and settled in 1856 in Minnesota where daughter, my great Grandmother Christina was born in 1857. She married my Great Grandfather in 1875 Wilhelm Kniefel in Faribault, Minn. I am wanting to confirm that the above were her birth parents, their genealogy and find for certain when they came to America. There does not seem to be any info in Ancestry.com prior to the 1860 Minn.census.
