I'm not a Thor/add-name-here shipper of any kind but I thought this was a good story. Frøya is pronounced FROY-uh.

Daughter of Sif
Prologue:
Lady Sif lay in her bed, leaning over, as she admired the life she had just created. The baby Asgardian girl was wrapped in a red velvet blanket.
"Welcome to Asgard, Frøya Thor'sdaughter. Or, maybe your name should be Frøya Sif'sdaughter," wondered Lady Sif.
She leaned back on her knees and picked up her newborn. Lady Sif walked to the crib and lay Frøya down. Lady Sif was a great warrior but that didn't mean she didn't want to be a loving mother. And, if it wasn't for Lorelei, Thor would want to be a loving father! No matter, Lady Sif was willing to give up her warrior ways for her daughter.
"Lady Sif,"
The new mother turned around and looked to see Odin. She immediately fell into a bow at the arrival of the All-Father.
"Odin... come to see your granddaughter?" Lady Sif asked, raising her head.
"No... Lady Sif, you are one of my greatest warriors and I would be honoured to have you as my daughter-in-law and mother of my grandchild but..."
"But, what?" Lady Sif asked, standing up and standing in the way of Frøya "I know Thor has fallen under the spell of Lorelei but I'm sure-"
"He assures me that is not what it is," said Odin, walking closer "Though that is obviously not true, he is my son so I will fulfil his wish,"
"Which is?" Lady Sif asked, reaching for her sword that leaned against the crib.
"For your daughter to be killed," Lady Sif swallowed her breath and took the sword, pointing it at Odin.
"I am sorry, All-Father, but I will not let you kill my daughter," said Lady Sif, taking her sleeping child into her other arm.
"Lady Sif," said Odin "Don't do this,"
Lady Sif walked backwards out of the room, keeping her eye on the grandfather of her child. She turned and ran from her room.
Lady Sif ran along the Bifrost, panting. Heimdall stood at the entrance and was confused by the urgency his sister ran.
"Sif, what are you doing?" Heimdall asked as she reached him, then he realized his niece "Sif, you had your child? What are you doing here?"
"Heimdall! Lorelei is truly wicked!" Sif exclaimed "She had Thor ask Odin to kill my child!"
Heimdall led Lady Sif inside. There was a roar of warriors looking for her in Asgard.
"What could I possibly do for you, Sif?" Heimdall asked "Odin will soon find you unless..."
"I go to another world," Sif looked at her daughter and tears began to fall from the warrior's eyes "They would find my Asgardian sent quickly but, Frøya, if she's raised by mortals..." Sif held her daughter closer "They won't be able to find her,"
"Sister, you don't mean you'll-"
"It's the only way she will be safe," Lady Sif said, she looked at her brother "Please, Heimdall, help me protect Frøya,"
Heimdall agreed and set the Bifrost to drop the baby Frøya at the edge of a populated area so it would be certain she'd be found. Sif looked away so she didn't know where her daughter was being sent and Heimdall prepared to erase the memory of Frøya's location from his mind.
Lady Sif stepped up to the portal with her daughter in her arms. She looked at the baby Asgardian with tears in her eyes. She was a warrior but her heart wasn't made of stone.
"Goodbye, Frøya Sif'sdaughter," Sif whispered to her daughter "I'll always be there for you,"
Sif stepped up to the portal and gently placed her in the way of the portal's pull. Frøya disappeared in the light and Lady Sif collapsed to her knees with tears running down her face.
