The information I have relates mostly to Matilda/Edith as her husband’s loyal regent during his frequent trips to Normandy. I have also found references to her good works, an interest in architecture and Henry’s apparent fondness for her despite his numerous mistresses and at least 22 illegitimate children, not all of them from before his marriage.
Kings having mistresses and illegitimate children was nothing unusual in medieval times, but Henry outdid even the Merry Monarch Charles II. Matilda/Edith certainly knew about most of this before she married him. Am I right in assuming that she simply accepted her husband’s philandering despite (probably) a lot of gossip behind her back?
Finally, I believe that the children were looked after by relatives and trusted servants but, although there are a number of references in the chronicles about the relationship between Henry and his children, I can’t find anything about Matilda/Edith as a parent. Do we know anything about her as a mother?
