You mention this about Annabel Lee a couple of times, but from what I can find that is no more than a local legend, and not generally accepted by Poe biographers, most of whom think he was referring to his late wife Virginia:

The aunt in question was the oldest, but I'm not sure by how many years, probably 5-6, but was certainly born in the early 1920s, in Appalachian Tennessee. Even in that time and place a girl of 13 marrying a man of 27 was considered kind of creepy, but not criminal with consent. (They consented because both my aunt and uncle said they'd run away together if they didn't - that itself would be quite criminal now.) Had she been, say, 16 instead of 13 it wouldn't have even been considered very abnormal, and wouldn't have even raised an eyebrow had she been 16 and he, say, 23. My aunt and uncle remained married, apparently happily, for the rest of their lives. He lived well into his 90s and she into her upper 80s, dieing a few years ago.
The past is a different country. They do things differently there.
