Algie

Algie was a wizard and the great-uncle of Neville Longbottom.

Neville's family initially believed he might have been a Squib, but Algie was determined to catch Neville off his guard and "force some magic" from him. He once pushed Neville off the end of the Blackpool pier however he nearly drowned. While over for tea one time when Neville was eight, Algie hung him out of an upstairs window by his ankles, and accidentally dropped him when he was offered a meringue by Enid. Instead of getting hurt, Neville bounced safely down the garden and out into the road, thereby proving that he was in fact a wizard. They were all so happy and Neville's grandmother Augusta Longbottom was crying.

Algie gave Neville his pet toad Trevor as a present for gaining entrance into Hogwarts School of Witchcraft and Wizardry in 1991. In 1995, he traveled to Assyria and brought back a Mimbulus Mimbletonia plant, which he gave to Neville for his birthday.
