> The table of 'who could not marry who' (at that time) is set out at the back of the 1662 Book of Common Prayer. Useful for 17th-21st century, but perhaps not for the twelfth century. Sibling marriages were the norm for the Pharoahs/gods of Egypt, but I doubt this is relevant to your researches! JK

Marriage between a brother and sister is forbidden in the Bible according to Leviticus chapter 20 verse 17. Modern translations use the word "marry", but my King James Bible translation is thus: " If a man shall take his sister...and see her nakedness...it is a wicked thing." Presumably at this time within the Christian Church the Latin Vulgate Bible would have been used, and I am no Latin scholar! We must assume that this relationship would have been banned within the Jewish and Christian faiths from the earliest times.
