I'm confused too. I went back and read some of the fans comments on the picture and most of them are posting the same thing: Voldemort got 'Marvolo' from his Grandfather's name (his mother's side). Voldemort's Father never had a middle name 'Marvolo'.BonusMage wrote:Then why doesn't it say Marvolo Riddle at the top instead of Thomas Riddle?, since that's the grandfather on the gravestone.
Its confusing.
In conclusion, it should say:
Thomas Riddle
1880-1943
Mary (I believe) Riddle
1883-1913
Tom Riddle
1915-1943
