It's Lyanna Stark. The reason for me thinking this is due to the flashbacks Ned was having in the first book.

"I promise," he whispered. "Lya, I promise..."

Page: 631
Promise me, Ned his sister had whispered from her bed of blood.

"Promise me" would be her telling Ned to look after John which she died giving birth to and for the bed of blood we all know giving birth to a baby is very bloody. For the farther it's not Ned, it's Rhaegar. When he got her pregnant either him or someone else sent her to that tower for her safety or for the unborn child. Rhaegar's family got brutally murdered so it wouldn't be far fetched for Lya to get murdered for having Rhaegar's child in her.

I also think if Ned told anybody he might have told Benjin.

When Jon says he doesn't care about never having kids Benjin replied "you might if you knew what that meant"

Ned was supporting him in joining the Nights Watch and nobody except TL told him the truth about it. I'm thinking Ned was supporting him in joining it not due to the North thinking it has honor, but because it would keep Jon safe if his secret got found out.

I don't know if it's in the 5th book but for the show Aemon says "A Targaryen alone in the world is a terrible thing" I know he was being read a message about Danny but he looked over at Jon when he ended that line. It's safe to say that line was meant for Jon as well due to the other past things.

I thought that was more about Aemon being alone in the world and pretty depressed about his family being systematically slaughtered, thinking he was the last one alive.

And Meera is Jon's twin sister. At the tower of joy Howland and Ned both each took a baby.
Meera and Jon both look alike and they were both supposedly born on the year that Lyanna died.

how very star wars

Also in the books meera and Jon don't look alike at all. She has brown hair and green eyes (if she was targaryean/stark she would have purple or grey eyes)

In other news, grass is green
