Disclaimer: I do not own anything from Harry Potter- Nor am I making any profit from this.

Disclaimer/ AN: I use some parts of the first few chapters of the book very closely to the original to show the few small changes that occurred, this will change once I hit a part where things start to diverge more, although this may occur again later in the story for specific conversations I believe need to stay the same or very similar to the original. I have done almost word for the last paragraph of the first chapter of the first book because it is my favorite paragraph in the series and wanted to give it a spotlight here. All recognizable writing from the books comes from J.K. Rowling and is not my work.

AN: Hey guys, I'm sorry I'm starting something new rather than continuing my old stories, but I've had horrible writers block along with complete insanity in my life recently so I haven't been able to write. I've done this idea before… more than once, but I'm hoping to do it better this time, as I'm a lot older then I was and I know where I failed before. So on that note, I hope you all enjoy.

Summary:

We've all read the stories or seen the movies, of a young wizard named Harry Potter. We've grown up or watched as our children grew up with stories of the Boy Who Lived. But what if something was different, what if he hadn't been alone at the Dursley's? What if Harry had a twin, a young girl named Katrina? How would things have been different? Well, you're about to find out.

July 31st, 1980- St Mungo's Hospital

Sirius Black sat in a row of chairs alongside his best friend Remus Lupin worry covering his features. Inside the room they could make out the sounds of Lily Potter screaming and cursing out her husband James. Peter Pettigrew rushed up juggling three mugs of coffee in his arms passing them around to the other two before taking a seat to wait with them. Hours passed the screaming dying down to the cries of a baby. The three men sighed in relief thinking it over before the screaming came again joining the wailing baby. Sirius stood up beginning to pace wanting to know what was going on. As the screaming died down again what sounded to be another baby's cry joined the first. The three friends waited with bated breaths as nurses came from the room followed by the doctor who gave them all a nod and grin before heading off. James Potter exited the room a while later a large goofy grin covering his face.

"It was Twins; The Doctor thinks the baby's heart beats must have matched perfectly for the muggles not have found the 2nd baby." He says excitedly to them. Sirius grins pulling James into a hug.

"Well Prongs when you do it, you really do it." Remus shakes his head at the bad joke his own grin not faltering. Peter squeaked in excitement.

"Come in you guys, and meet the newest two Potter's" James says ushering them all into the room, before rushing back to Lily who was lying tiredly in her bed holding two bundles of Blue and Pink.

"How are you Lill's?" Remus asks as he enters giving her a kind smile.

"As good as to be expected I suspect, I think I have Alice beat having had to deal with two deliveries even if hers took longer." She laughs jokingly smiling down at her two little miracles.

"Well what are their names, and who's older" Sirius presses coming over to peer at the two babies'.

"Well the oldest is our son Harry James Potter" James says motioning to the blue bundle.

"And then we have Katrina Lillian Potter, our little surprise" Lily says looking down at the bundle of Pink where a little baby stared up at her with wide eyes.

"Well we have the new Potter Prince and also a Princess" Sirius teases. James just grins at his friend.

"We wanted to ask you something Padfoot?" Sirius looks up curiously.

"We wanted to make you Godfather of the twins" Lily says smiling at him sweetly "We would have made you one as well if it where legal Remus." She explains. Remus just nods understandingly and grins at Sirius waiting for the reaction.

"You're serious?" He asks shocked he'd be trusted with something as important as this.

"No that would be you." James says snickering. Lily shaking her head in annoyance.

"Of course I'd love to be Godfather, now on that note can I hold my godchildren?" The others laugh at his puppy like excitement, each taking turns to hold the newest members of their little family.

Their twin children one year olds Harry and Katrina Potter became legends to the wizarding world, the two having survived the Killing Curse, a curse no one had ever survived before. The only thing left to show this, was the matching lightning bolt scars on their foreheads, and the defeat of Lord Voldemort promptly ending the eleven year long war for the wizarding world. The twins where taken by a man named Rubeus Hagrid to Dumbledore who left them on the doorstep of their mothers sister and her husband along with a note explaining what happened.

November 1st, 1981- Number 4 Privet Drive

A breeze ruffled the neat hedges of Privet Drive, which lay silent and tidy under the inky sky, the very last place you would expect astonishing things to happen. Harry Potter rolled over inside his blankets without waking up. One small hand reaching for his sisters beside him; Katrina Potter grasped her brothers hand her other closed on the letter between them. The twins slept on, not knowing they were special, not knowing they were famous, not knowing they would be woken in a few hours' time by Mrs. Dursley's scream as she opened the front door to put out the milk bottles, nor that they would spend the next few weeks being prodded and pinched by their cousin Dudley. . . . They couldn't know that at this very moment, people meeting in secret all over the country were holding up their glasses and saying in hushed voices: "To Harry and Katrina Potter – the twins who lived!"
