This little girl was the stillborn daughter of Edward Jacob and Clara Opal (Hughes) Schwarck, born 17 May 1920 in Mercer County, Ohio.  Her father was born in Auglaize County, Ohio, and her mother was born in Jay County, Indiana.
Edward and Clara married in 1915  and lived in Blackcreek Township with a Willshire address. The family attended Zion Chatt for a time, where Clara and another daughter, Mary Naomi, were baptized in 1916.
Their stillborn daughter had an older sister, Mary Naomi, born in 1916, and later a brother Louis, who was born in 1923 and died later that same year. This child is buried next to her brother Louis. Edward and Clara eventually had another daughter, Pauline, born about 1928. 
Edward Schwarck worked as a pumper in the oil fields around Chatt before the family eventually moved to the Sandusky, Ohio, area, where he continued to work in the oil fields. Edward died in Toledo in 1964  and Clara died in 1989. Both are buried in Greenlawn Cemetery, Wapakoneta, Ohio. 
This surname is spelled Schwark in Zion Chatt’s records.
