Katherine or Kathrine "Kay" Winthrop McKean (July 17, 1914 – February 12, 1997)[1] was a top-ranked American tennis player, who, in 1936 at Wimbledon, played doubles with Alice Marble.
[9] Before World War II she was in tour in South America with Jack Kramer, Sarah Palfrey and Bobby Riggs.
[1] Winthrop gave up competitive tennis in 1970, aged 56, but continued to play socially for many years later.
They met at a cocktail party while McKean was still married to his first wife, painter Margarett Sargent (1892–1978).
[5] McKean had bought the Samuel Corning House in Beverly, Massachusetts in 1920 (which was listed on the National Register of Historic Places in 1990).
