Fanny loved her oldest brother, Gus. In her diary, she makes notes about his quiet personality and controversial career. Gus chose a career in the military and fought in the Mexican American War and the Frontier Wars. The Sewards, especially Frances, disapproved of this choice. Gus did not write very much when he was out west, and he later came to Washington to be a paymaster in the Civil War. He never married and never had children. If Fanny had remained unmarried and lived longer, she may have become closer with her bachelor brother.
“she asked me to come and spend the evening with her daughter “Sarah,” there were to be a few friends there. Invited me to “bring a beau”...I asked Augustus, he said he would take me there, leave me, and call for me again–he is very averse to society, and never goes out.” Jan 20, 1863
