In Block 57 of Oakland Cemetery is a tombstone which honors the memory of Johannes and Catharine Leidorf. Johannese Leidorf was born May 12, 1804 in Germany, and died in Erie County, Ohio on December 11, 1879. Catharine Leidorf was born February 11, 1816 in Germany and died in Erie County on December 8, 1894.
THE HISTORY OF ERIE COUNTY, ed. by Lewis Cass Aldrich, states that John and Elizabeth Catharine (Wagoner) Leidorf came to the United States in 1845, and settled in Margaretta Township. Their children were Conrad Leidorf, and Elizabeth Leidorf, who married Henry Schoewe.
the 1860 U.S. Census for Erie County lists John/Johannes' surname as Ladorf, and his birthplace as Hesse-Kassel. It is not unusual to find spelling variations in both the first name and surnames of individuals in genealogical records, especially in families of German origin.
