|Portrayed by||Louise Barnes|
Miranda Barlow was a resident of Nassau. Unknown to most, she and Flint had a relationship, but even those who knew about it do not know the full extent.
Barlow was originally from London where she was known as Mrs. Thomas Hamilton. Her husband, Thomas was close friends with a naval officer, James McGraw. Thomas' father, the Earl Alfred Hamilton, had been Lord Proprietor of the Bahama islands at some point in the past. Her affair with McGraw began when she invited him to view Egyptian artifacts at a friends home. Following her husband's death, she and McGraw move from London to Nassau, where she is known as "Mrs. Barlow", and he becomes the notorious pirate captain James Flint.
Miranda first appeared following Flint's successful duel against Singleton. She helped him recover by bandaging his wounds. She would eventually be asked by Flint to provide a safehouse for Richard Guthrie who was then a fugitive and was convalescing from a gunshot wound he received in the shoulder. Barlow dutifully treated Guthrie and eventually began to form a friendship with him, in particular over the book "Meditations" by Marcus Aurelius, which she had given Guthrie to read during his recovery. When Flint found out that she had been discussing the book with Guthrie, he became incensed with her. Flint would later reveal to Billy Bones that he and Barlow's greatest shared interest was with books.
During her time in Nassau, Barlow would repeatedly be visited by Pastor Lambrick, who was always trying to get her to engage him in conversation. The times that she did speak with him, she often played the role of devil's advocate to his spiritual teachings. Lambrick told Barlow that she was mistrusted by many among his "flock". This is evidenced when a local boy throws a rock at her and calls her a witch one day while she was gardening. During one of her conversations with Lambrick, Guthrie snuck around her house and found a painting of her and her late husband. It was then that Guthrie found out who she really was. He later confronted her about it and attempted to entice her to go to Boston, where she could begin a new and cultured life like the one she had left behind when she left London.
When the crew of the Walrus captured the Andromache, Billy Bones found a letter on the Andromache that was written by Barlow. The letter was to the authorities in Massachusetts. It stated that Flint was a good and decent man who was willing to give up the pirate life. In the letter, Barlow pleaded with the authorities to accept and forgive Flint once he betrayed his crew.
One evening, Pastor Lambrick came to Barlow's house very late in the evening. He stated that he was concerned about her safety because Richard Guthrie had recently taken up with a powerful local landowner and he feared that her association with Flint would put her in danger. Barlow told Lambrick that she was perfectly safe and that she knew the real reason why he came: because he wanted to have sex with her. Barlow then proceeded to seduce Lambrick and the two had sex, albeit very briefly.
