Hepzibah Smith

From Hpwiki

Hepzibah Smith, a descendent of Helga Hufflepuff, was murdered by Tom Riddle so he could steal a cup belonging to Helga Hufflepuff and a heavy golden locket that had belonged to Salazar Slytherin from her. He pinned the murder on her house-elf, Hokey. If it wasn't for the fact that Smith is a ridiculously common name, one might suggest that she may be related to Zacharias Smith. (Although, it may bear mentioning that both the names 'Hepzibah' and 'Zacharias', which are not as common, are both Hebrew.)
