Hagrid found the twins crying in their cribs later that night. He borrowed Sirius's motorcycle, and flew them to Privet Drive in Little Whinging. dismounting the bike, he greeted the two people waiting for him. "Professor Dumbledore, Sir. Professor McGonagall."
"No problems, I trust, Hagrid?" Professor Dumbledore asked as he looked at the twins sleeping in the basket.
"No, sir. Little tykes fell asleep just as we were flying over Bristol. Heh. Try not to wake them. There you go." He passed the children to Dumbledore, who showed them to Professor McGonagall.
"Albus, do you really think its safe, leaving him with these people? I've been watching them all day. They're the worst sort of Muggles imaginable. They really are." She protested as they began to walk towards house number ten.
"The only family they have." He set them down on the front steps of the house.
"These children will be famous. There wont be a child in our world who doesn't know their names."
"Exactly. They're better off growing up away from all that. Until they are ready." He went to place a letter in the basket when McGonagall held back his hand.
"No. I will raise them as my own, and as a muggle until they are ready to go to Hogwarts. Albus, I resign as Professor of Transfiguration, Deputy Headmistress, and as Head of Gryffindor House. I suggest Mr. James Potter takes my place as Head of House, and find someone to become the next transfiguration teacher. I am adopting these two, and you won't be able to find me. This is good bye, Albus. I will see you when my children become your students."
Minerva McGonagall then picked up the basket containing the two toddlers, and walked over to the side of the road and held out her wand. Seconds later, a purple triple-decker bus pulled up to the curb. Minerva walked onto the bus and left Hagrid staring alongside Professor Albus Percival Wulfric Brian Dumbledore, speechless at his former Deputy Headmistress's actions.
"Leaky Cauldrun, please." Minerva said, after paying the fee to travel on the bus.
Once she'd arrived, she woke Old Tom, the Barkeeper, and had him open up a room for her. After spending a sleepless night watching her children sleep. 'The poor, wee bairns,' she thought. 'They don't even know that their parents are gone.' she cried silently, knowing that her children would be forced to become heroes and public figures by the time they were students.
Once the morning came, she took the children to Saint Mungoes to check the cuts on their heads. When the Medi-witches told her what was within the cuts, Minerva asked "Is there anything you can do?"
"No, marm. But the Goblins do. I know most people avoid them, but they are the only creatures that can do this without hurting the children."
Minerva wasted no time Flooing herself and the children to Gringotts. She walked up to an old friend of hers among the Goblins of Gringotts. "Griphook, may I have a word?"
Once Griphook closed the door on the consulting room door, he said "What do you need, Minerva? I was in the middle of a profitable transaction."
"I need you to remove soul fragments from the cuts in my children's heads."
"Very well. Stand back." Griphook looked first at the boy, then placed a fingernail on his cut. The child whimpered as Griphook seemed to pinch a piece of black smoke, which he placed into a glass jar. He then repeated the process with the girl, doing the same to her. He then took from a small vial from his pocket , and dripped three drops of liquid into each bottle. When the smoke inside the jars dissipated, he said "I have repaid my debt to you for all time. I hope to do business with you again in the future, Minerva."
"Thank you Griphook, and I do have some business to deal with considering Identity changes."
"Oh?"
"Dumbledore was going to leave these two with the worst possible people. So, can you get me an identity as a Muggle, along with these two?"
"I will. Would you like for me to also withdraw a substantial part of your family's vaults for transferral to a Trust Fund in one of our Muggle Branches?"
"Yes, and some money for me to have with me now."
Griphook nodded. "What would you like to be known as?"
"Minerva Stewart."
"And the children?"
"My grand children, Harry Severus Stewart, and Titania Lilly Stewart."
Griphook nodded. "And their parents?"
"Disappeared while the children were being watched by me one night."
"Very well. That should be enough information to go by. Do you require anything else?"
"A house in Maybrind, Scotland. No magic whatsoever on it. The place has to have a large yard behind it, and a cottage big enough for three adults. "
"Consider it done, Miss Stewart."
"Mrs. Stewart. My husband died in the Second World War. I raised our son David on my own in London, where he met Danielle Prince."
"Very well, . "
When Griphook returned with the papers, he handed them to Minerva along with a billfold. "This is Muggle money. Do you know how to use it?"
"Yes. One of my best friends as a child was a muggle. I'll be fine."
Griphook chuckled as he held out a key "Here is the key to your farm's house. And this is your account at the Royal Bank of Scotland." he handed her a file. "This has a list of investments that you've bought and they will pay out good sums of money to give you a steady income. It also has a trust fund for you to purchase certain items you will need on the farm. There's a young couple that live on the next farm over, and you might want to meet them." Griphook smiled.
"How can I ever repay you?"
"You don't, Minerva. I just hope that the twins will be safe." he shrugged. "They mean a lot to us Goblins. Teach them to be kind. That's all we ask."
Once Minerva left Diagon Alley, she went to the nearest bus station, and traveled by bus to Maybrind, with the children seated beside her. She found her way to their house, and happily entered after seeing the wheat wreath on the door.
