I am looking for a Mary Preisen born 26 July 1844 Germany. The family immigrated in 1855 and appears on the 1860 census in St. Anthony. She is on the ship with the family. I don't know if she died before arriving in Minnesota or not. She does not appear to be buried at St. Anthony cemtery with the rest of the family. I am also looking for her brother Thomas born 7 Dec 1841 Germany. He is on the 1870 census but I can't find him on the 1880 census anywhere. He is not buried at St. Anthony cemetery either. The surname was also spelled Prison, Preusen, Prussia, etc. What other cemeteries should be checked? Thx Tom
