Mrs. Charles Fairchild  (Elizabeth Nelson Fairchild 1845-1924).

Sargent sent this painting off to be exhibited it at the New English Art Club that same year. Mrs. Fairchild was a poet and was often a hostess of parties for artist friends. It was probably through one of these social gatherings that John first met them.  It would be Mr. Charles Fairchild that would prompt the third portrait of Robert Louis Stevenson by commission as a gift for his wife. 

Her husband Mr. Charles Fairchild (1838-1910) was a Boston banker and, according to Olson, would come to handled all of  Sargent's finances when he was in the States. It would be through Mr. Fairchild that John had painted his brother's portrait who had been the Governor of Wisconsin (Lucius Fairchild) and war hero -- the same year he painted Charles's wife (1887).

They also commission Sargent to paint the third protrait of Robert Louis Stevenson.
