text_A: The use of the title "First Lady" to describe the spouse or hostess of an executive began in the United States. In the early days of the republic, there was not a generally accepted title for the wife of the president. Many early first ladies expressed their own preference for how they were addressed, including the use of such titles as "Lady", "Mrs. President" and "Mrs. Presidentress"; Martha Washington was often referred to as "Lady Washington". One of the earliest uses of the term "First Lady" was applied to her in an 1838 newspaper article that appeared in the "St. Johnsbury Caledonian", the author, "Mrs. Sigourney", discussing how Martha Washington had not changed, even after her husband George became president. She wrote that "The first lady of the nation still preserved the habits of early life. Never indulging in indolence, she left the pillow at dawn, and after breakfast, retired to her chamber for an hour for the study of the scriptures and devotion."
text_B: Is it likely that Mrs. Washington's contemporaries approved of her as a First Lady?
YES.
