As the Door Banged Siegfried walked towards it and opened the door to see a giant of a man standing at 11'6" he had a mane of shaggy black hair and a beard that covered most of his face. The Giant's hands were as big as dustbin lids a. He was wearing a a brown overcoat that seemed to have to many pockets. (Check the Wiki for more information).

"Hello, is there something I can help you with sir?" Asked Siegfried the giant of a man. "Hello there, I'm lookin' fer 'Elen Potter and Arry Potter. I believe that they live 'ere." Said the Giant.
"Mind introducing yourself first sir?" Said Siegfried. " Where are my manners. Name's Rebeus Hagrid, I work fer Hogwarts school of Witchcraft and Magic." The giant of a man introduced himself. "Wait you are the guy that the letter mentioned?" Asked Helen as she Came forward in front of Hagrid.

"Ello there, Elen, look at how much you've grown, I bet that you will grow up like yer mom one day." Said Hagrid as he looked at Helen, causing Helen to look at the man suspiciously.

"How Do you know my Parents." Asked Helen as she looked at Hagird with Slight Suspicion.
"Oh, of course I knew 'em they also attended Hogwarts." Said Hagrid. "My parents were Mages?"
"Of course they were." Said Hagrid. "Then what are their names then?" Asked Helen in order to confirm if the Man in front of them really knew her biological Parents. "Their names were Lily Potter nee Evans, an' James Potter. James was born in March 27 1960 and Lily was born in January 30 1960. The Hogwarts Records keep all the names of the students that attended the school." Said Hagrid. 

"Ok Say we believe you? What's in it for me and My brother." Asked Helen as she decided to humor the giant of a Man gave them a card with an address at Charing Cross Road, then when Helen and  looked up to see that the Hagrid had mysteriously vanished.

"That was odd?" Said Helen. "I agree so you wanna check out the address tomorrow?" Asked Siegfried. "Ok, And I believe that we've got to tell Harry and bring Kiana along." Said Helen. "No big problem" Responded Siegfried, then the two returned inside.

"Who was sis?" Asked Harry as he looked at his sister. "I think it was the staff member the Academy the letter told us." Said Helen. "Dad is Magic Real?" As Kiana as she looked her father. "I guess so little Comet." Responded Siegfried and Kiana looked at her adopted siblings with stars in her eyes. "You two are Magicians?!" Asked Kiana with excitement lacing her tone.

"That remains to be seen little sister. That remains to be seen little sister." Said Helen as she patted her younger sister's head like a cat and Helen giggle.
