Son of William FitzGerald, 2nd Duke of Leinster, Fitzgerald joined the navy in March 1809, passed his examination in 1815, and was commissioned in March 1826. Soon after his arrival in Western Australia in 1848, Fitzgerald accompanied Augustus Gregory on an expedition in the Northampton region where Gregory and his brother had discovered lead the year before. An encounter with Aborigines resulted in Fitzgerald being speared in the leg and at least three Aborigines shot dead.
The town of Geraldton, Western Australia was named after him.
