My father is Raymond Frederick Luth born in Riley Twnsp, Marengo, IL in 1900(d.1970).His parents were Gustave Luth(b.1866 d.1949)& Mary Kappelmann(b.1876-d.1927)(spelling of her name varies from document to document). They married in 1896. His parents were Gustavus Luth(he arrived in the USA in 1841 from Germany-he had died by the time the 1880 Census rolled around. He died between 1875-1880) & Louise Hohmann(b.1833-she married Gustavus in 1861). Mary's parents were Ernst(b.1846 in Germany-d.1901) & Magdelina(b.1851-in Germany-d.1913-came to USA in 1871) Kopplemann.Another different spelling but the same family.
If any of this information sounds famiiliar let me know.I'm trying to find their German ancesters.
