On 14 July 1926, Wyman married a wealthy obstetrician and medical school professor named Henry McMahon Painter (12 July 1863 – 11 March 1934), whose patients include members of prominent New York families. According to Minton, Wyman and Painter had been lovers for many years; earlier in 1926 Painter had obtained a divorce from his wife. Painter retired from medicine in 1928; Wyman moved with him to France, where they lived in Grez-sur-Loing, an artist-colony village not far from Paris. They later returned to New York, where Painter died in 1934.
