Do any midrashim etc detail the names and background of each the wives of the sons of Jacob?
I know the book of Jubilees does, but that is not considered 'canonical'.
Besides that, I only know of the few mentions we get in the Torah of a couple of the wives and daughters - Judah's Canaanite wife Bat-Shua, then Tamar, and that Joseph married Asenath, who could be either Egyptian or Dinah's daughter by Shechem's rape, depending on interpretation (plus the mention that Asher had a daughter called Serach).
Aish seems to reckon that they generally all married foreign women who converted: https://aish.com/conversion-in-biblical-times/?gclid=CjwKCAjwjMiiBhA4EiwAZe6jQ0dFkz2tQdIIziYfT_LE-4OGOWyu2EgFw4388cqU9pZg2-5ueEV9SBoCYhQQAvD_BwE
I'm aware that there is also the interpretation that each of the Shevatim was born with an accompanying unmentioned sister, but that points towards all of them marrying their half-sisters, which seems a bit much even for the Torah, especially if we go with the tradition that they all followed the laws (or tried to) even before it was given.
Edit: Further on this, Shemida seems to be named as a son of Manasseh according to Numbers 26:32, Joshua 17:2, and 1 Chronicles 7:19. We hear that Manasseh's unnamed wife bears Asriel and that Aramiah/Amoritess concubine bears Machir and that lineage continues to Gilead, but it's then unclear who bore Shemida, Helek, Hepher etc (these all seem to be Manasseh's sons, although I've also seen them described as Gilead's sons). Any clarification?
