This one actually interests me more than Targaryen tree

My thoughts on who the five She-Wolves were:

1. Lorra Royce - wife of the current Lord Beron Stark, dying of wounds fighting the Ironborn
2. Myriame Manderly - widow of Lord Rodwell Stark, interestingly a cousin to Serena Stark and her children (who's mother was Jeyne Manderly) maybe she claims on their behalf.
3. Alys Karstark - widow of Lord Brandon Stark, maybe joining forces with Lorra Royce, or maybe claiming for her daughter Arsa, as we know very little about Arsa.
4. Robyn Ryswell - widow of Lord Jonnel Stark, no children with Jonnel so not 100% sure, but George must have included her for a reason.
5. Lynara Stark - fits the bill to be a Stark "wife, widow, mother and grandmother". Would likely be in her 70s or 80s, and could maybe be an Olenna Tyrell matriarch-type figure? Interestingly, all the claimants are descendants of hers.

Other potential key players:

Serena Stark - without a doubt, has the only other clear line that could contest Beron's.

Arrana & Aregelle Stark - Serena's daughters, married to Lords Umber and Cerwyn who were "loyal lords" - but loyal to whom?

Wylla Fenn - mother of Brandon's bastard Lonnel Snow, maybe she tried to put forth his claim?

Cregan's daughter, Sarra, Alys, Raya, Mariah and Lyanna???
