Her death record listed her mother's maiden name as Crabb.
She was born in 1924 in Cuyahoga, Ohio. Her birth record states "additional information: John" which suggests that is her dad's name (you should order the whole record to be sure - state file number 192044287). This is most likely her and her family in the 1930 census for Cuyahoga, Ohio:
--JOHN H. HOERGER, head, b. about 1890 Indiana to parents born in Kentucky (father) and Indiana (mother). Occupation: crane operator for a building supply company
--GRACE HOERGER, wife, b. about 1886 Indiana to parents also born in Indiana
--VIRGINIA HOERGER, daughter, b. about 1925 Ohio
--GERTRUDE HOERGER, daughter, b. about 1915 Ohio
--JOSEPHINE HOERGER, daughter, b. about 1916 Indiana
--ELIZABETH HOERGER, daughter, b. about 1923 Ohio
According to her death certificate, Grace was born about 1886 and died as a widow in Marymount Hospital, Garfield Heights, Cuyahoga, Ohio on July 15, 1967 (you can order her death certificate; it might list her parents)
This appears to be John in the 1900 census with his family:
--SAMUEL C. HOERGER, head, b. March 1863 in KY to parents born in Germany, married 1882
--LOUISA HOERGER, wife, b. April 1864 in Indiana to parents born in Germany
--JOHN H. HOERGER, son, b. Dec. 1889 in Indiana
--CHRISTOPHER HOERGER, son, b. Nov. 1882 Indiana
--FLORENCE HOERGER, daughter, b. April 1885 Indiana
--HAMPTON S. HOERGER, son, b. May 1892 Indiana
