What is the name of Fitzgerald's only child?

Fitzgerald’s only child was Frances Scott “Scottie” Fitzgerald. She was born on October 26, 1921, in Saint Paul, Minnesota, to novelist F. Scott Fitzgerald and Zelda Sayre Fitzgerald.

Her name honored her father’s full name, Francis Scott Key Fitzgerald, while “Scottie” became her familiar nickname. Fitzgerald often wrote about his hopes for her future, even as the family’s life was disrupted by his financial difficulties, alcoholism, and Zelda’s recurring hospitalizations for mental illness.

Scottie later attended Vassar College and became a writer and journalist. She worked for publications including The Washington Post and The New Yorker and was active in Democratic Party politics. Her life differed sharply from the glamorous fictional worlds most associated with her father’s novels.

A likely source of confusion is Zelda’s name: Zelda Fitzgerald was Scottie’s mother, not another child. Fitzgerald and Zelda had no other children. Scottie married Jack Lanahan and had four children, making Fitzgerald a grandfather. She died in Montgomery, Alabama, in 1986 and was buried near her parents in Rockville, Maryland.
