Klaus, Hayley and Hope

The family relationship between Klaus Mikaelson, Hayley Marshall-Kenner and their daughter, Hope.
Klaus and Hayley conceived her in Mystic Falls after that Klaus saved Hayley from Will. They dealt with Hayley's pregnancy with Hope and the fact of becoming parents during the first season of The Originals. As Hayley's pregnancy progressed it became clear that Hope is the thing that they love the most in the world. Klaus had a nursery built for Hope next to Hayley's room in the Abattoir where they would live as a family. Hayley gave birth to Hope in From a Cradle to a Grave while Klaus (weakened by Genevieve's Moonlight Rings) and her were captives of the New Orleans Coven, who wanted to sacrifice Hope to follow Klaus' mother, Esther's decree. They killed Hayley and left Klaus unconscious. However, Hayley was resurrected by Hope's blood and she went with Klaus to retrieve her baby with the help of Klaus' half-brother Elijah Mikaelson. They managed to rescue Hope, but then Klaus and Hayley decided to give her away to Klaus' half-sister Rebekah Mikaelson to protect her from the people that are trying to kill her. They decided that once New Orleans was safe, Hope would return home to Hayley and Klaus; this was Klaus' promise to her.
They are reunited in The Map of Moments where Klaus and Hayley are finally able to enjoy parenthood. However, when Hayley decides to leave New Orleans with Hope and her pack, following her new husband's advice, Klaus found them and cursed the Crescent Wolf Pack, including Hayley, and took back Hope. Over the next six months, Hope remains under the protection of Klaus, while Hayley is only able to see Hope once a month on a full moon.
With her curse put on temporary hold in You Hung the Moon, Hayley is finally able to fully reunite with Hope and take custody of her from Klaus. Hayley now lives in an apartment across from the compound, within range of Klaus' protection and in his eyesight, with Hope and Jackson. In The Axeman's Letter the curse is permanently lifted by Davina Claire.
Hayley and Klaus resolved their problems by the end of season three and agreed to work as partners for Hope. After Klaus sacrificed himself to save the family Hayley spent five years raising Hope and searching for ways to bring their family back. Hayley kept Klaus' memory alive for Hope as she told her daughter things about her father such as his loyalty to his family and how much he loved her. Hope deems her father as her 'fairytale prince'.
Hayley saved the family after five years of their various ailments and worked with the Mikaelsons to save Klaus who was held in captivity by Marcel. They succeded and brought him home where he was reunited with Hope. Klaus and Hayley resided with their family and raised Hope as partners while fighting to keep their family together. Hope was sent to the Salvatore School in Mystic Falls during the period of time when the Hollow was divided into the four Mikaelson siblings.
Following Hayley's death in What, Will, I, Have, Left and Klaus' death in When The Saints Go Marching In, Hope has been oprhaned.
They are known as Klaylope or Klopley.
