Have found in 1920 census an Edward Aldrich, age 48, widowed, born Ohio, father born Massachusetts,mother born Penn. Occupation dealer, horses. He was living in Green Creek Township, Sandusky Co. Ohio. Living with him are sons Clayton, age 14, Ralph age 12 and Ivan age 9. I hope this is the one you are looking for. Also the National Aldrich Association has a wonder site and there may be someone who would have additional information. They are a great group and have many resources.
