Disclaimer: I don't own Harry Potter, it belongs to the rightful owners. I only own Ella.
A/N: Just to let people know, this is a completely different story to A New Prophecy so you don't need to have read that to read this. Also, I will still be updating A New Prophecy even while writing this.
James Potter sat at the fireplace of his home in Godric's Hollow, with his baby son Harry. Harry was just over a year old and James's youngest child - his daughter had turned two only the last month. Part of him was glad that Gabriella (or Ella to her parents) and Harry were so close in age, with just eleven months between them. Their daughter had been named by one of James's cousins, who lived in France but wrote to him when their daughter was born asking him to name the child after her. He'd accepted for two reasons - he liked the name and it would make his cousin happy. While his wand displayed lights to entertain his young son, James stared into the fire.
Lily had fallen pregnant with their daughter in December 1977, while they were still at Hogwarts. Luckily, his mother Euphemia had cared for Lily and Professor Dumbledore had sent her assignments and exams there to be sat. Lily had easily passed everything and Ella had arrived on the 25th September 1978. James remembered his pride seeing his daughter. James and Lily became Aurors, managing to juggle being Aurors with being parents. Euphemia and Fleamont were happy to take their granddaughter when James and Lily had important business.
Then in October 1979 Lily was pregnant again. The timing felt terrible, their daughter had only just turned a year old the week before and now they would be having another child. Another thing that made the timing terrible was that James's parents had recently died of Dragon Pox meaning there was nobody who could take the children while James and Lily were busy - Sirius Black, their daughter's godfather, Remus Lupin and Peter Pettigrew were all busy with the Order and would therefore be unable to have the children.
Harry was born on the 31st July 1980. Sirius and Remus came to visit mother and child in hospital - a Muggle hospital as they were now in hiding from Voldemort who wanted to destroy their son. They kept their visit brief and secret, not wanting Death Eaters to find out where Lily and the baby were. Sirius had brought Ella, whom he'd agreed to look after until Lily and Harry returned to Godric's Hollow. This gave James time to prepare the nursery for a second child, adding in another crib and repainting the room from pink to yellow, a more neutral colour.
Lily came home in August, bringing Harry with her. Ella's first birthday came the month after that. James had given his daughter a new teddy as well as a toy broomstick ("She'll be the best at Quidditch when she's at Hogwarts") while Lily had brought home a cat for Ella - Lily had a cat at Hogwarts and she wanted her daughter to love them as much as she did. Sirius brought the girl some sweets, mostly Every Flavour Beans and Chocolate Frogs, and also brought her a beautiful music box which played by itself whenever someone was in the room. He and James then proceeded to eat the sweets themselves upon Sirius's realisation the girl was too young for the sweets. However, she loved the music box. Remus had brought dresses for Ella and Peter Pettigrew gave the child a book of fairy tales for her birthday. Lily and James thanked their friends for their consideration in these presents for Ella.
A year later on Harry's first birthday, Sirius had given Harry his own toy broomstick so he wouldn't have to share with his sister. Sirius loved both of his godchildren although James had the feeling he favoured Harry slightly - Harry was almost a spitting image of James except for his green eyes the same as his mother's. Ella on the other hand looked more like her mother, though she had her father's black hair and hazel eyes.
It had been three months since Harry's first birthday, James thought to himself as he stared into that fire. He froze hearing the gate of the cottage, quickly handing baby Harry to Lily.
"Take Harry and Ella and run! I'll hold him off while you get the kids out of here!" James told his wife, who nodded and ran upstairs to wake Ella. The door was opened and Voldemort appeared in front of James.
"Avada Kedavra!" Voldemort quickly used his spell. James's body fell to the ground and Voldemort just casually stepped over it before heading upstairs. He entered the nursery and saw Lily Potter in the nursery. Ella was asleep in her bed while Harry had been placed in his cot.
"Lily. Move aside and you and your daughter may leave alive." Voldemort offered - he only needed the baby boy dead, the prophecy made no mention of his mother or sister.
"Never!" Lily moved in front of her son's crib, glaring.
"Very well. Avada Kedavra!" Voldemort ruthlessly killed the woman, stepping over her body to get to the baby which had begun crying at his shouts. The girl was also beginning to waken. The dark lord pointed his wand at the boy, but when he used the Killing Curse things didn't go to plan…
