1441 (aged 51)
Gifford Ollerton (1390—1441) was a wizard famous for his reputation as a giant-slayer, having killed the giant Hengist of Upper Barnton, who terrorised the small town of Upper Barnton in the fifteenth century.
Gifford Ollerton was born in 1390, somewhere in the British Isles. If he enrolled at Hogwarts School of Witchcraft and Wizardry, he attended the school from around 1401 to 1408, under Headmistress Phyllida Spore.
In the fifteenth century, giant numbers were relatively big in the British Isles, when compared to today. Wizards became professional giant-slayers in order to restrict these numbers and to protect wizarding communities.
The giant Hengist of Upper Barnton terrorised the small town of Upper Barnton, in England, at somepoint during the fifteenth century. Gifford Ollerton, at the time a fully-fledged wizard rushed to the village's aid, and famously defeated the giant, becoming celebrated as that town's local hero.
Gifford Ollerton died in 1441, at the age of fifty-one.
