Muggles' Guide to Harry Potter/Characters/Caractacus Burke

Overview
Caractacus Burke is one of the owners of Borgin and Burkes, the Dark magic supplies store in Knockturn Alley. The other owner is Borgin.

Half-Blood Prince
In Albus Dumbledore's Pensieve, Harry sees Burke gloating over the marvelous deal he had made, buying the Locket of Slytherin for about ten Galleons from some poor little witch, almost certainly Merope Gaunt, who didn't know what she had. He evidently later sold it for thousands of Galleons to Hepzibah Smith.

Analysis
Due to the fact that Borgin & Burke's seems to be exclusively ran by Borgin during Harry Potter's time, it's possible that Burke died sometime within the next fifty-some years of when we see him in the Pensieve. To add to this theory Dumbledore claims that Caractacus was one of the original founders of the shop in 1863, and so must have been born before 1846. Evidence in the stories suggests that Tom Riddle was born about 1930, and would have started working for Caractacus when he was about 18, in or about 1948. So Caractacus would have already been at least 100 by the time Tom Riddle began working for him.
