Finding 'Petunia Marries Sirius' fanfiction can be a bit of a treasure hunt. One tip is to look for fanfiction that explores alternate universes or 'what - if' scenarios in the Harry Potter universe, as this type of plot often leads to unique pairings like Petunia and Sirius. You could also try searching for authors who are known for writing unconventional pairings in the Harry Potter fandom.
One possible plotline could be that in an alternate universe, Petunia and Sirius meet under different circumstances. Maybe Petunia has a more magical inclination than in the original story, and Sirius sees something in her that draws him to her. Their relationship then develops against the backdrop of the wizarding world's politics and the ongoing struggle against the Dark Arts.
I'm not sure of the exact name, but there are some fanfictions where Sirius marries Narcissa that focus on the political implications in the wizarding world. Their marriage could be a way to bridge the gap between the pure - blood families who were on different sides of the conflict. These fanfictions often create a whole new dynamic in the Harry Potter universe.
Well, there's 'The Unlikely Bond'. In this fanfiction, it starts with an accidental encounter between Petunia Evans and Sirius Black. As the story progresses, they find themselves drawn to each other in unexpected ways. It shows how two very different characters from different sides of the magical divide can form an interesting connection. There are also some really well - written descriptions of the magical world from Petunia's point of view, which is quite refreshing.
A common theme is the exploration of how their personalities would mesh. Snape is often portrayed as a complex and somewhat tortured character, while Petunia is more down - to - earth and practical. How they deal with each other's flaws and strengths is a big part of the story. There's also the theme of secrecy, as Snape has a lot of secrets in the wizarding world that he may or may not share with Petunia, which can create a lot of tension in the relationship.
In a fanfiction where Petunia meets Sirius, it could be a very interesting encounter. Sirius, being a wizard from the wizarding world, might shock Petunia at first. He could show her some simple magic, like making a flower bloom, which would both terrify and fascinate her.

One of the most interesting scenarios could be when Petunia and Sirius are forced to team up for a common goal, like protecting Harry from a new threat. Petunia would have to rely on Sirius' magic skills, and Sirius would have to trust Petunia's knowledge of the Muggle world. Their interactions during this time would be full of tension, misunderstandings, but also potential for growth and understanding.
One common theme is the exploration of the divide between the Muggle and wizarding worlds. Since Petunia is a Muggle - born adjacent character and Sirius is a pure - blood wizard, their interactions often highlight the differences and similarities. Another theme is redemption. Sirius may be seen as trying to make up for past mistakes through his relationship with Petunia.
