Have two generations of one family ever won a medal at the same Olympics?

Question

Nino Salukvadze and her son Tsotne Machavariani have both qualified for Rio 2016 Olympic games.

Has it ever happened in the past that two generations of the same family have won a medal in the same Olympics? (including both winter and summer Olympics)

Answer 1

Yes, here's an example: Alfred and his father Oscar Swahn (Sweden) - 1912, shooting, team gold.

Oscar is particularly interesting, "At 64 years of age, he became the oldest gold medalist ever, which he still remains up to today."
