Fire, Ice, Lighting and other forces I don't own anything except oc charecters

Lily P.o.V I look my two child and I feel worry but happiness to having them one is my biological child other is blood adopted but James and I love them equally.
My Harry and Mimosa, sweetest children in world and still end is near to all of us.
James is optimistic but I'm not so much.
I rub my pregnant belly, I watch Harry and Mimosa sleeping in Mimosa's small bed with all purple like her original eyes... Black eyes like Regulus had and little Mimosa's real mother Bellatrix has.
Sirius kidnapped or as he calls it saved her.
Mimosa real name was Chromaggia Aquila Lestrange, daughter of Bellatrix and Rabastan, but Sirius did take her when they were visiting in Black manor and he gave her to us.
She is my daughter and I gonna raise her in safe from all this madness. I'm not sure if I did right thing by taking her in since Bellatrix turned even madder but I love Mimosa she is our daughter even if not by birth.
I look my house all the memories, all happy moments are there.
This new pregnancy came in worst possible time and some part of me wanted end it but I couldn't.
James and I have talked about names and if baby is boy we name him Ryan and if baby turns to be girl we planned name her Andrea.
I hope that everything turns aright but I fear the worst.

Some months later...
Peter betray us, and I know that lord Voldemort is coming to kill us.
Suddenly door is blow away and James yells at me to take kids and run away. Like hell I can runaway since kids are in upstairs.
I know what I have to do, teleport ritual which I read at Potter manor. I run upstairs and I grip old or more like ancient book (ancient magic and rituals for safety of realm by Brandon Stark) and I run to Harry's room were my children are.
They are sleeping at Harrys crib, which is good thing.
I start performance ritual and I hope I have enough time.
Suddenly he is in and my babies wake up and Harry stares at me worried, he truly have my eyes and otherwise he is all of his father.
Dark lord tells me to move but I know lie when I hear one.
Ritual is almost over all I need to do is sacrifice of blood and life.
I take knife and stab myself same time Avada Kedavra is cast and hit's me.
Then there is loud boom and everything goes to dark and I feel hot sensation of burning.

Same time in Westeros It's first anniversary after Roberts rebellion.
Comet is flying over Kings landing and there is atmosphere of change, but what one knows it that change bigger than nobody can except and dawn of new era is beginning.
Soon there is three babies to be born in the different great houses and smaller houses and balance of world is going to change forever.

So houses to our characters Harry is going to be either: Greyjoy, Baratheon, Arryn or Dayne Mimosa: Stark, Bolton, Estermont or Lannister Unnamed baby (vote for gender): Arryn, Mormont, Clegane or other if you guys have idea.
And if you wishes for paring I'm open suggestions.
But I was thinking Harry with some of these Roslin Frey, Myrcella, Asha/Yara, Margaery or Sansa Mimosa: Jaime, Tyrion, Willas, Margaery Unnamed baby: Sansa or Dany if it's boy and girl well Tommen, Jon or Robb
