Trying to trace Fred and Martha. I can find Fred in 1880 and 1900 census. He was born abt 1860/61 Mecklenburg Germany. He married Martha 2 Jun 1881 Cuyahoga Co. Martha appears with Fred in 1900 and without him in 1920 and 1930 although she states as being married. Can not find her in 1940. Martha was born abt 1865 Ohio. Would like to find death for both if possible.
