On November 21, 1827, she married Rev. Ira M. Allen, then of
Brandon, Vermont, but who became, in 1830, the agent of the Baptist General Tract Society and removed in the discharge of his official duties to
Philadelphia. Here, she united with the Sansom Street Church, then under the pastoral charge of the Rev. John L. Dagg. Allen was the third editor, taking over in 1840. Having fewer personal responsibilities than the previous editors, Allen was able to give more time to preparing articles for its pages and in correspondence with friends to interest them on its behalf. At the same time, her husband became employed by the
American and Foreign Bible Society, and they moved to
New York City. Allen never enjoyed perfect health. Before her marriage, sickness brought her close to death. After that event, at Brandon, and for a time in Philadelphia also, she was the subject of a spinal affection which caused great suffering and disabled her from walking. Relieved from this, her constitution continued to be feeble. Still, she remained active in the order of her household, her interest in various societies, and her literary employment. ==Later life and death==
