AN: This story is based off another story I read about Letters from Draco to his parents. I thought that I could do something similar with Harry and Astoria as there aren't enough pairings with them.

Dear Mum and Dad,
I had such a great time at the Yule Ball with Harry Potter! I'm so glad you let me go with him! He was so charming and handsome, we danced almost the entire time! I included some pictures of us at the Ball, enjoy!
Please write back and love you bunches,
Astoria

Dear Mum and Dad,
I got your letter about not talking to Harry anymore. I understand our family's neutrality and such but Harry is my friend. I'm not just going to abandon him. You should meet him, you might like him.
Love you bunches,
Astoria

Dear Mum and Dad,
That Professor Umbridge is a right butthole. She is using a blood quill on the students who get detentions with her and Harry has "I Must Not Tell Lies" engraved into his hand! I'm trying to be good and whatnot but I just want to strangle that lady!
Write back soon and love you bunches,
Astoria

Dear Mum and Dad,
I'm glad that Professor Umbridge is gone from Hogwarts and You-Know-Who is back in the open again. I also got your second letter about leaving Harry alone but he was really hurt at the Ministry so I need to be there for him. You need to understand.
Love you bunches,
Astoria

Dear Mum and Dad,
Harry asked me to Professor Slughorn's Christmas party! I'm so excited! I'll send some pictures of us with my next letter! I'll see you at Christmas Break!

Dear Mum,
Please don't show this letter to Dad please. The other night Harry went with Headmaster Dumbledore on a mission and later Death Eaters raided the castle and killed Dumbledore. Was Dad there? I understand if he was. I just hope that he doesn't have to fight Harry. He is wicked with a wand!
Love you bunches,

Dear Mum and Dad,
I have decided to go with Harry on an adventure over the summer. Don't worry about me, I'm a big girl! I'll hopefully be back for sixth year but I don't know. Anyways, see you when I get back!
Love you bunches,
Astoria

Dear Mum and Dad,
I can't tell you much but I'm safe. I decided to skip 6th year and continue the adventure with Harry and Hermione. His one friend, Ron, abandoned us a while ago but it's okay. He ate a lot of food so no loss there.
See you when I get back and love you bunches,
Astoria

Dear Mum and Dad,
I saw you at Malfoy Manor with You-Know-Who. I want you to know that I understand. You have made your choice and I, mine. I'll see you at the Manor after a while.
Love you bunches,
Astoria

Dear Mum and Dad,
I saw you at the battle. Like I said, I understand. I also felt through my magic that you disowned me yesterday. I hope Daphne is able to bring you grandchildren that can continue the Greengrass line. Also, Harry proposed to me after the battle! We are getting married in December so there is snow! You both know I have always wanted a winter wedding! I'll send an invitation when we make them!
Love you bunches,
Astoria (Soon to be Potter!)

Dear Mum and Dad,
Me and Harry would love if you could make it to our wedding on the 26th (it's a Saturday!) of December at the Godric's Hollow Chapel. We are hoping it's small but Harry thinks that the Minister of Magic will be there! Exciting!
Love you bunches,
Astoria

Dear Mum and Dad,
I'm sorry you couldn't make it to our wedding. You should have seen the decorations! I felt like a Princess with all of the ice sculptures and Christmas trees! I have included some pictures we took as I know Mum loves pictures!
Love you bunches,
Astoria Potter

Dear Mum and Dad,
I know you ignored Harry sending you a letter about coming to see me in the hospital, but I wanted to let you know that the Heir Potter was born at 8:39 pm on November 20th. He was 51 cm tall and weighed 3.3 kilograms! Me and Harry decided to name him, James Valerian Potter. His middle name is named after you, Dad. I have included some pictures of us plus Harry (sometimes). I haven't heard from Daphne recently, tell her she is always welcome at Potter Manor just like you two are.
Love you bunches,
Astoria Potter

Dear Mum and Dad,
I didn't realize that sending a child to Hogwarts was so hard. We sent James on the first and it was so sad! I cried when me and Harry got home. I bet that was what mom did when me and Daphne went to school. Also, I wanted to let you know that I'm pregnant again! Harry says it's a girl but I think James is going to have a little brother!
Love you bunches,
Astoria Potter

Dear Mr. and Mrs. Greengrass,
I regret to inform you that your daughter Astoria, be that disowned or not, died suddenly in childbirth on December 19th. Our daughter, Lily Astoria Potter, was safety delivered, however complications arose and Astoria died a few hours later. I know you don't like me and, at this point, maybe even Astoria, but I hope you can put aside your problems and attend her funeral. She will be buried next to my parents in Godric's Hollow. I have attached the last few pictures we have of her holding Lily and with us as a Family, for your records or whatever you have that Astoria kept sending you pictures for.
Best Regards,
Lord Harry James Potter-Black

Dear Mr. and Mrs. Greengrass,
Thank you for your presence at Astoria's funeral. I expect she was smiling from Heaven when you attended. I have included a picture of just your Grandchildren, as you requested. I will send you a picture of them every Christmas so you know how they are growing.
Thanks again,
Harry

Dear Lord Potter-Black,
As much as I dislike your politics, I wanted to let you know that I have restored Astoria to the Greengrass line as Valerian has passed. As Daphne hasn't had any male heirs, I expect the James will have to become Lord Potter-Black-Greengrass when he comes of age. I also wanted to ask if you and your children would like to have Christmas at Greengrass Manor this year. I would like to get to know my grandchildren and their children before I die. I have many regrets over my lifetime, please allow me to have this one mercy.
Love you and your family bunches,
Alice Greengrass
