From The Bison, the yearbook of Howard University, 1930.
Elaine A. Du Bissette graduated from Howard University in Washington, D.C., in 1930 with a degree in education. Per her yearbook entry, she was a native of Grenada, British West Indies, and graduated Wilson High School [sic] in Wilson. As shown here, she received her high school diploma in 1926.
Du Bissette was clearly a close relative of Dr. Michael E. Dubissette, but their exact relationship is not clear. Was she his niece? Younger sister? Child from a previous marriage? (This seems unlikely, as he did not declare on his naturalization application.)
Hat tip to S.A. Stevens for pointing out this yearbook entry.
