Looking for any info on Rosa Luxemburg born in Germany in 1846. No, not the political activist with the same name! My Rosa Luxemburg immigrated to the U.S., I do not know the date, or where she sailed from. She married a man named Urban Stocker, who was himself an immigrant from Switzerland. Rosa and Urban married and lived out the rest of their lives in Cook co. Illinois. They had a daughter named Jennie Margaret Stocker, who married Stanley Case. Rosa died in Cook co., in 1925. Any info as to who her parents were, or where she came from in Germany, would be appreciated.
