|Lavender Brown's Wand|
Garrick Ollivander (most likely)
The wand of Lavender Brown is of unknown length, wood and core. Like most wizards in Great Britain she most likely purchased her wand at age eleven from Ollivanders Wand Shop before starting her education at Hogwarts School of Witchcraft and Wizardry in 1991.
It is unknown what happened to the wand after Lavender's death in the Battle of Hogwarts.
