The Adventures of Lavender Potter

Background

Voldemort never had the time or the inclination to make horcruxes. He died with Quirrell in May 1992.

In June 1992,as the Wizarding World celebrated Voldemort's final death,Amelia Bones led a coup that instated Rufus Scrimgeour as minister of magic. She also had Sirius Black brought before the Wizengamot,as he hadn't had a proper trial. They judged him innocent and he adopted Harry at the end of 1992.

The Triwizard Tournament was held in 1993 and 1994,at Hogwarts, but with Ilvermorny substituting for Durmstrang as that school was undergoing an administrative crisis following the suicide of Headmaster Igor Karkaroff. Fleur Delacour was the Beauxbatons champion,Oliver Wood was the Hogwarts champion,and Forrest Kelleher was the Ilvermorny champion. Hogwarts won the championship.

Harry Potter's Fourth year was quiet,as Remus Lupin made marriage plans for him. Sirius suggested that Harry marry one witch from each Hogwarts house to demonstrate interhouse unity. 

On June 24,1995,Harry was officially betrothed to Penelope Clearwater for Ravenclaw,Susan Bones for Hufflepuff,Lavender Brown for Gryffindor,and Millicent Bulstrode for Slytherin. They were married on June 25,1996,by Sirius Black,in the Church of St.Anthony in Godric's Hollow. In the same ceremony Harry's best friend Ron Weasley was wed to Pansy Parkinson,his friend Neville Longbottom was wed to Su Li,and Ron's sister Ginny married Ernie Macmillan.  Hermione Granger has expressed interest in Viktor Krum,the acting (and youngest) Headmaster of Durmstrang.

As the 1996-1997 school year begins at Hogwarts,Albus Dumbledore has retired to devote his time to writing a history of the Greater Good War (1936-1945). At his request,Minerva McGonagall has succeeded him and from August 15,1996, is the Headmistress of Hogwarts, the 18th individual to hold that title. Harry has done well in his OWL tests and looks to become a Historian of Magic, while his wife Lavender looks to become a Herbologist and his wife Millicent looks to become an Auror. Penelope works in the Quidditch Regulation Division and Susan would like to become a Wizziotherapist.

Oh,and all myths are true.

PS. As for Peter Pettigrew,he reconverted back to human form in early 1993 and killed himself by drowning in Loch Shiel. Ron always wondered what happened to his pet rat Scabbers.
