My parents - your grandparents - they put it here when it became clear that the police weren't gonna find my body. They visit every week, and they bring flowers, even though there's no one buried here. The Isobel they knew is dead. So maybe there's a part of me buried here, the human part, the part that I abandoned when I chose to become a vampire, the part that used to dream about the day that she'd know her daughters. And instead you got to meet the other part... The part that would betray her own flesh and blood. I'm so sorry, Alex, Elena... That I was such a disappointment to you guys.
Isobel's last words and saying goodbye to Elena and Alex in Know Thy Enemy


Isobel Flemming was the wife of Alaric Saltzman and the biological mother of Arielle Labonair, Elena Gilbert, and Alexandria Gilbert. She is also the grandmother to Hope Mikaelson, Jaxon Salvatore, Nikolina Gilbert-Salvatore, Lillian Gilbert-Salvatore, Grayson Salvatore, Sarah Salvatore, Miranda Mikaelson, Jenna Mikaelson, Stefanie Salvatore, and Nik Mikaelson. She is also the adoptive grandmother to Adella Gilbert-Mikaelson. She was good friends with her ancestor Katherine Pierce, a vampire she often conspired with. When Isobel was still in high school, she met John Gilbert and became pregnant with Elena and Alex.

After being compelled by Klaus, she committed suicide by walking into the sun while her daughters Elena and Alex watched.

Isobel was a member of the Petrova Family and Labonair Family and a former relative of the Saltzman Family due to her marriage with Alaric. She was also a relative to the Gilbert Family, as she was Elena and Alex biological mother. She also has ties to the Mikaelson Family and Salvatore Family due to Alex's marriage to Niklaus Mikaelson and Elena's marriage to Damon Salvatore.
