The swimwear styles, particularly the man's high-waisted patterned trunks and the young woman's halter-neck suit, strongly indicate the late 1930s to early 1940s. Cross-referencing with the genealogical data, identifying the subjects as Albert Fox (b. 1896), Leona Fox (b. 1921), and one of the younger sons (b. 1930/1931) aligns perfectly with a date around 1939, making them approximately 43, 18, and 8-9 years old respectively.

The swimwear is highly indicative of the late 1930s. The man wears high-waisted, patterned trunks, a style popular before the transition to lower-cut styles in the 1950s. The young woman wears a modest one-piece with a halter neck and a slight skirt, paired with a functional swim cap, typical of the era's beachwear.
