"

In keeping with her image as a country girl, Patterson brought two Jersey cows to the White House.[7] The cows pastured on the lawn and Patterson milked them daily, "don[ning] a calico dress and a spotless apron."[7] Just before the execution of Mary Surratt, her daughter Anna came to the White House, hoping to persuade Johnson to spare her mother's life. Denied access to the president, she lay weeping on the stairs to his office and was comforted by Patterson, who said there was nothing she could do to stop it.[citation needed]
