My 2nd great grandparents Mary (Ware) and James Hardy Cass were buried at Evergreen Cemetery, Fort Atkinson, Jefferson County, Wisconsin.
Mary Ellen (Ware) Cass was born February 10, 1861 in Hancock, Waushara County, Wisconsin. She died March 27, 1921 in Fort Atkinson, Jefferson County, Wisconsin.
Census records prior to 1900 vary from 1850 - 1852 as far as the year James Hardy Cass was born; census records after 1900 indicate he was born in 1851 - I do not know whether the grave marker is in error. In any event, James Hardy Cass was born October 17, 1850 (or 1851) in Oakland, Jefferson County, Wisconsin. He died on April 15, 1923 in Norwood Park, Cook County, Illinois.
