Thomas Riddle (1880–1943) was a very wealthy Muggle who owned most of the town of Little Hangleton. He and his wife Mary had a son named Tom. The Riddles were snobby and looked down on most other people in town, in particular the poverty-striken Gaunt family that lived nearby.
Thus, they suffered great scandal when Tom abruptly married Merope Gaunt, the daughter of "tramp" Marvolo Gaunt. The pair left for London, but Tom soon returned his parents' home, claiming to have been "hood-winked" and "taken in" by Merope. This may have referred to her being a witch and probably using a Love Potion on him to obtain his affections, or to her pregnancy.
Riddle's grandson, Tom
In 1943, Tom was confronted by the son he had abandoned — Tom Marvolo Riddle, who had been left in an orphanage after his mother's death and who was a very powerful wizard. Thomas was murdered by his grandson with the Killing Curse, as were his wife and son. Riddle then framed his uncle Morfin Gaunt for the crime, and he was imprisoned in Azkaban, while the Muggle authorities could not figure out how the Riddles had died, but many suspected their gardener, Frank Bryce, of being the killer.
