There is a Martha Stauring b. abt 1844 listed in the census with John and Rebeca, however, this John appears in census data through 1870. He is the son of John/Johan Stauring/Stahring and Catherine Fuchs/Fox. From user submitted ancestral files, Rebecca is the daughter of Johannes and Polly Casporous. Don't know if any of this helps. Maybe searching some of the siblings will provide more info.
