Hello there! My first fanfiction. I am Dutch but I wanted to write in English so if it isn't written in the right way with spelling and all, please review and let me know!

I have to do this: I do not own anything accept for my own characters! Unfortunately I am not JK Rowling.

In short, this is a story about Rosella Ariana Dumbledore. She is the daughter of Voldemort and Alliana Dumbledore.

She doesn't know this. Alliana and Albus Dumbledore keep this a secret for her. Rosella become's best friends with Neville, just because I truly love Neville and how he becomes! She also becomes friends with Hermione, Harry and Ron.

Hope you enjoy! And please review!

( just a little side info, I have changed all the confusion around the cousin/niece/grandfather thing. If it's still around please tell me! Also put in some additions in some chapters, but not to much. )

Chapter one

Alliana was gasping for air and screaming in pain. Minerva Mcgonnagle was holding her hand and even with all the screaming and Alliana squeezing her hand really hard, Minerva didn't looked uneasy or uncomfortable. If anything she was a great support for Alliana who was having her baby right now.

"Just one more push honey!" said madam Pomprey. "Then you're all done."

With a last scream Alliana was indeed done and the cries of her newborn filled the hospital. Madam Pomprey was laying the baby down, lifted her wand and said the spell that would tell her if the newborn was alright.

"It's a beautiful baby girl my dear."

Minerva was washing the sweat of Alliana's forehead and was comforting her with soft whispering words.

"Is she alright?" Alliana asked out of breath.

Madam Pompry was still checking the baby while the baby was turning into different shades of red and orange and finally her pink normal color. Madam Pomprey looked up.

"She's alright," madam Pomprey said while putting a blanket around the baby. She gave Alliana her daughter. "Did you think of a name yet?"

"In all the confusion of the last weeks, I kind of forgot to even think of a name." Alliana admitted tiresome. She looked at the little girl in her arms. She was not crying anymore but let out little cute baby sounds. Even Minerva Mcgonnagle, who was normally very stiff and strictly looking, smiled at the sight of it. The baby girl grabbed one of Alliana's long black curls. Alliana smiled. She saw that her daughter had deep, dark blue eyes. It was unusual but it didn't concern her, she thought it was beautiful, everything about her daughter was beautiful.

"Can we come in?" a friendly voice asked.

"Yes you can," Madam Pomprey said.

Sirius Black came in and looked although al little bit concerned, very happy, he was followed by Severus Snape who was looking down and grimy as usual and finally Albus Dumbledore who looked like he just accidentally walked into the room. He smiled widely and walked over to Alliana and kissed her on her forehead.

"Well done dear niece," he said. Alliana smiled to him.

"It's a girl," Alliana said to them.

"What are you gonna call her?" Sirius asked. Alliana looked at him. Over these few months they had grown very fond of each other. She blushed a little as he smiled to her. Then she looked at her daughter again. Thinking of the name.

"It's going to be Rose," she said. "Rosella Ariana Dumbledore."

"Not Riddle?" Severus asked.

Alliana nodded her head. "No, she's taking my last name and her great aunt's Ariana's name. I like the flower Rose and in a bed time story my mother used to read to me there was a heroin named Rosella. So her full name will be Rosella Ariana Dumbledore and she will be called Rose after my favorite flower.

"Those are beautiful names Alliana." Minerva sighed.

"Now you all need to go, she needs her rest. It's not every day a woman gives birth," madam Pomprey said with her strict voice again.

"I'll take her for a bit my dear niece," Albus said as his hands reached out to Rose.

Alliana nodded and kissed her baby on the head before she gave it to her Uncle. Albus, Minerva, Sirius and Snape left the bed and Madam Pomprey pulled the curtains shut.

Albus Dumbledore looked at the girl which was sobbing a little but was over all very quiet. It was 2 o'clock in the morning. So Rose was born on the night of the 11th of August. He looked at her unusual dark blue eyes and knew he loved her and would protect her with his own life.

A few weeks later….

Alliana was sitting in the Headmasters office. She had been here before when she got in trouble in her 5th year at Hogwarts. She got into a fight with a Slytherin girl, named Cindy Gorfitch. She had called her a blood traitor and Alliana, who normally never picked a fight, couldn't take it and had cursed her so that three weeks later she was still barfing out snales.

The previous headmaster let her off with some detention and a warning not the curse anyone but Cindy Gorfitch had the clean the toilets with a toothbrush. Alliana laughed a little bit at the memory of it. She had thought she was in a lot of trouble but it worked out fine, her uncle Albus who was now headmaster, put in a good word for her. The previous headmaster thought she was in her right to stand up for herself and it was unusual for Alliana to get in trouble.

Now however there was a far different reason she was her now and she wasn't a student anymore. She had left Rose with Minerva and Severus. And now she had to talk to Dumbledore. He wasn't there yet. But Minerva had told her to wait for him there.

A few moments later Dumbledore arrived. "Good afternoon Alliana."

"Good afternoon, Albus. Everything went alright?" she asked concerned

"Yes," Dumbledore nodded as he sat down behind his desk. "I explained to James and Lily how the spell works and that they had to find a Secret Keeper. I volunteered of course but James and Lily insisted on getting Sirius."

"It's sounds like you regret their decision, taking Sirius as their Secret Keeper. You don't trust him?" Alliana asked. She had got very close to Sirius since she had called out to Albus. He was her uncle, the brother of her father Aberforth Dumbledore. They hadn't spoken in 2 years.

That was because she was with Voldemort. He had romanced her and charmed her into coming with him and join him. At first she fell for him but that was only two weeks, after that he kept her a prisoner. He had only wanted her to take revenge on Albus because he was fighting against him. Alliana first didn't know why he kept her alive but then learned Voldemort wanted an heir and what better revenge to conceive a child with the niece of his number one enemy. He found her fitting to give birth to his heir.

About 4 months ago she managed to escape with the help of Severus who got her to meet up with Albus and then got her to Hogwarts where she and her newborn would be safest.

Sirius was very comforting to her and they became good friends. She didn't understand why Albus would be so untrusting towards him. He was James and Lily's best friend. He would rather die than give away their hiding place.

"I suspect that there is a spy from the Dark side in that group of friends. I don't know if it's Sirius but I do not want to take any chance. They are too important to us." Dumbledore explained.

Alliana nodded. She liked James and Lily. Lily had come to Hogwarts for a couple of times and helped her with Rose. She took her son Harry who was only a month older than Rose. She was very kind and became a good friend to her as well.

"But now we need to talk about Rose's future." Dumbedore carried on.

Alliana nodded again. Although they were pretty save at Hogwarts, Voldemort wanted his heir back. Severus had told them it was now the top priority under the Death Eaters.

"You will have to stay here with Rose it's the safest," he carried on and Alliana nodded. "But it cannot last forever, if Voldemort is the one winning this war, not even Hogwarts will be save for you and Rose. You understand that?"

Alliana sighed. "Yes I do."

"Good you need to know that, that could be a reality. But I want to give her extra protection. With your permission, I want to make an Unbreakable vow to protect her with my own life."

"Albus?" Alliana was a little surprised. "I know you will do that no matter what. You don't have to do that!"

"On the contrary," Albus replied. "I feel like I have no other option to make your daughter more save. She is in a lot of danger. I do not know what Voldemort will do to her but I do not want her to grow up with such a dark and twisted man. It would break my heart so I want to make this commitment to her. And to you as well."

Alliana looked at his eyes that always seem to know her deepest thoughts and fears. Then she sighed deeply. She saw that he was determent and she knew that her daughter would be safest this way. Albus wouldn't want it any other way.

"Ok, I will accept," she said firmly.

Albus Dumbledore smiled encouraging to her. "Alright Ill call for Severus he will be performing it."

Severus Snape performed the Unbreakable vow for them as Albus pledged that he would always protect Rose with his life.
