“The Darchei Moshe and Rema demonstrate Rabbeinu Gershom provided exceptions to the Cherem, such as if the wife couldn’t have children. This effectively establishes that prior to R”G’s Cherem no such exceptions were necessary for polygyny.”
got it, though
I’m not questioning if it was allowed.
Of course it was.
I am looking for a source as to how it was done in practice.
The Remah does imply that there were such places “ועיין בי”ד סי’ רכ”ח אם הלך ממקום שנהגו להחמיר למקום שנהגו להקל”
Thanks
“As far as Tanach or Chazal, they didn’t always tell us everyone’s full marital statuses, ”
