About the polygamy issue, I think Florys isn’t a good example, since Florys kept 3 husbands, but each ignorant of the other two (an extraordinary feat I’d say), so on their view she was monogamous. Btw how do imagine she accomplished said feat (I know it’s kind of a legend but still I’d like to hear your thoughts)

goodqueenaly:

But again, given the historical example of polygamy in pre-Andal Westeros (the one cited by Yandel, anyway) is ALSO from the Reach, I don’t think it’s stretching to say that integrating the idea of multiple spouses for a single partner into the mythology of the region came from real practices in that same region. As for how, I sense it probably varied from storyteller to storyteller, with all focusing on some clever trick of Florys to keep her husbands in the dark.

Also, the polyandry of the ancestors of House Tarly was quite open.
