She met and formed an attachment with John A. Logan, 13 years her senior, while working with her father in Shawneetown. Mr. Logan was then an ambitious young lawyer, the prosecuting attorney for the third judicial circuit of Illinois, residing in the town of
Benton, Illinois. They married November 27, 1855, when she was 16 years old, and at once went to the young attorney's home at Benton where he opened a law office. Though she was reared a Baptist, after her marriage she joined the Methodist Church, the church of the Logan family. He was re-elected to the Legislature in 1856 as a Democrat. During this term in the Legislature he became quite prominent through his advocacy of very important measures, and as early as 1857, was called by a colleague in the Legislature the "Black Eagle of the South." The title being suggested by his vigor and independence and very dark complexion. Mrs. Logan immediately identified her interests with those of her husband and in many ways she contributed to his many successes in the political world. She accompanied him on all his professional journeys, an undertaking in those days of wildernesses and no roads, often requiring great endurance and privation. A son, John Cunningham Logan, was born in 1856 but died the following year. Also in 1856, Mrs. Logan saw her husband elected a member of the Legislature, and in the Douglas and Lincoln Senatorial contest, he was elected as a Douglas Democrat to Congress. In all the political campaigns, the wife went with her husband, assisting in much of his Work of correspondence and copying, and frequently receiving his friends and conferring with them on the details of the campaign. When Mr. Logan came to Congress as a Representative, Mrs. Logan came with him. She remained with him in Washington until the outbreak of the
American Civil War, when he resigned his seat in Congress to return to Illinois to go into the service of his country. With the war commencing in 1861, and Mr. Logan assigned to the command of the 31st Illinois Volunteers, Mrs. Logan and daughter
Mary (nicknamed "Dollie", 1858–1940) returned to Capt Cunningham's home at Marion. The Illinois troops having been ordered into camp at
Cairo, Mrs. Logan joined her husband there. During the battle of Belmont, Mrs. Logan cared for the wounded soldiers as they were brought back from the bloody field. When the army entered upon the Tennessee River campaign, Mrs. Logan again returned to her home, but was soon shocked by the news from Donelson that her husband had fallen at the head of his charging columns, dangerously wounded. She hastened to the scene to care for her husband, a struggle between life and death. At Memphis, in the winter of 1862–3, Mrs. Logan again joined her husband, now a general, and remained there until he led his troops in the campaign which ended in the surrender of Vicksburg. During this time, and to the end of the war, Mrs. Logan remained at Carbondale, where, out of the General's salary, they had bought an unpretentious home. Upon his return from the war, General Logan was nominated by acclamation for Congressman-at-large. After his election, Mrs. Logan returned to Washington and became a prominent figure in Washington society. After his service in the
United States House of Representatives, General Logan was elected to the
United States Senate. At the time of his nomination for the vice-presidency with
James G. Blaine, it was she who restrained the impetuosity of her husband, who would have scorned the nomination, and prevented any differences between the leaders of the party. It came as a terrible blow to Mrs. Logan when the General became sick and died in 1886. She decided a change of scene would help her and so she traveled through Europe, chaperoning
George Pullman's daughters. On her return, Mrs. Logan became the editor of
The Home Magazine, of Washington, which ran from 1888 to 1908, writing reminiscences of historic events. She served on the syndicate staff of Hearst news service, was a contributor to other magazine and newspapers, and wrote several books. President
Benjamin Harrison appointed Mrs. Logan one of the women commissioners of the
District of Columbia to the
Columbian Exposition (Chicago, 1893). She also worked on plans for the
Garfield Memorial Hospital, having been president of the board nine years. Logan died at her home in Washington, D.C. in 1923 and was buried beside her husband and two of her grandsons in a mausoleum at the
United States Soldiers' and Airmen's Home National Cemetery. Effects from her estate were put up for auction by
C.G. Sloan & Co., Washington, D.C., in1924. ==Calumet Place==
