According to research, the only important dates I was able to relate to this poem are as follows. "Annabel Lee" was the last poem that Poe composed, and was first published in November, 1849, in The Southern Literary Messenger, a month or so after his death. Written in 1849. Poe’s death occurred on October 7, 1849. "Annabel Lee" appeared in two newspapers, the Richmond Examiner and the New York Tribune, and then in the 1850 edition of The Works of the Late Edgar Allan Poe. In 1836, he married his cousin Virginia Clemm after receiving an editorship at The Southern Literary Messenger in Richmond. His wife Virginia died from tuberculosis in 1847. After a period in which he was involved in various romantic affairs, Poe planned to remarry, but in late September, 1849, he arrived in Baltimore for reasons unknown. In early October he was discovered nearly unconscious; he died on October 7, never regaining sufficient consciousness to relate the details of the final days of his life. I am not sure if this is what you need or if this is even helpful at all, but hopefully it will be.
