This pushes the limits of what I know, but the names, dates and locations are close.
There was a (John) Daniel Rauscher who immigrated in the mid-1830s, lived for a few years in Stark County, Ohio, then moved to Dubois County, Indiana, patenting land there in 1839.There is a Rauscher cemetery near Huntingburg, Indiana on land that he originally patented.
He was married twice.His first wife is reported to have died enroute to the US.They had at least one child, Jacob, who farmed in Patoka Township, Dubois County, Indiana.
His second wife was apparently Susanna Schwartz and they married in Stark County, Ohio shortly after Daniel's arrival. Children that I knew of, include Gottlieb (b. 1834, Ohio), Christian (b. 1837, Ohio), and Daniel (b. 1840, Indiana).
My ancestor, Christian Schwartz, may have been a brother of Susanna's.He also married in Stark County, Ohio and moved to Dubois County, Indiana at the same time.He patented 80 acres (as Christian Black) near the 200 acres Daniel Rauscher patented on the same day.Christian Black was guardian of the Rauscher children.He moved to Illinois, lived near Lancaster and is buried in the Lancaster cemetery.
You might find a paper trail in the guardianship papers in Dubois County, Indiana (1840s).
