The Eastern Washington University has a great newspaper archive and I found these items about the students at Cheney.
The February 1924 issue features Jean under the Biology section. Edna is under the English listings. Miriam has graduated but here are a series of 1924 photos of the sisters except Vivian.
The March article you will find Jean’s name under Biology and Modern History. Eddie appears under the English students.
A close up of the March 1924 article on Honor Students has a little article tucked in at the end about the girls basketball team receiving the honor of letters. Eddie is listed.
“Twelve members of girls’ basketball teams at the Cheney high school have been awarded honor letters as follows: Clare Bemi, Adelia Bacharach, Vivian Harmon, Alice Ewy, Edna McDonald, Alberta Victor, Theresia Burke, Virginia Nance, Genevieve Johnson, Gertrude Bechtel, Elizabeth Andrews, Juanita Eads.”
