Don't forget all the Targs, Ned Stark and his growing family whose kids are also starting to get married, the Frey's since you're dealing with their drama right now, Cersei and Stannis and their kids along with the whole Lannister clan. I've barely scratched the surface and my head already hurts. lol.
Mya Stone, that one dragonseed girl Robert has, the daughter of that big titty mother. The three bastard daughters of Wylla who Kelsey is one. Cassana and Lyrra the daughters of Lyanna, Steffon the youngest son but heir to the throne.
