As a Harry Potter fan, I can say with confidence that Sirius Black never got married. Throughout the series, there is no mention or indication of Sirius being married. He was known to be a fiercely loyal friend, particularly to James Potter and later Harry, but his romantic life was not explored in the books.
However, it is worth mentioning that there are some fan theories suggesting that Sirius Black may have been married to Marlene McKinnon. Marlene McKinnon was a member of the original Order of the Phoenix and was mentioned as one of the casualties of the First Wizarding War. Some fans speculate that Sirius and Marlene had a secret relationship and even got married before her untimely demise.
Nevertheless, it is important to note that these theories are purely speculative and not supported by any concrete evidence from J.K. Rowling or the books themselves. They are merely products of fans’ imagination and interpretation of the story.
In the absence of any official information regarding Sirius Black’s marital status, it is safe to assume that he remained unmarried throughout his life. His focus seemed to be on fighting against Voldemort and protecting Harry rather than pursuing romantic relationships.
While it can be intriguing to speculate about the personal lives of fictional characters, it is crucial to distinguish between what is canonically established in the books and what is merely fan conjecture. In the case of Sirius Black, his marital status remains a mystery, making him an enigmatic and intriguing character in the Harry Potter universe.
There is no definitive answer to the question of who married Sirius Black. While some fans enjoy theorizing that he may have been married to Marlene McKinnon, there is no concrete evidence in the books to support this claim. As far as the official canon goes, Sirius Black’s marital status remains unknown, leaving room for speculation and imagination.
