  • Notes 
    • Many sources show him as a bastard son of Eustace of Boulogne by an unknown mistress. In "The Parentage of Geoffrey fitz Eustace (c. 1045-1105)" (Foundations 10:98, 2018), Kim Anderson and Richard Joscelyne make a good case that he was probably a legitimate son of Eustace by his first wife, Godgifu.

      Was Godfrey the crusader the same Geoffrey that married Beatrice de Mandeville? This claim pops up in many places; people doing personal genealogical research are most likely to encounter it in David H. Kelley's essay in Ancestral Roots, eighth edition (line 158A). The short answer: No.

      Both were sons of Eustace II, albeit by different mothers. The claim that they were a single person doesn't hold up. Todd A. Farmerie: "Murray's analysis takes the sole argument in favor of this connection, that the names Geoffrey and Godfrey were, at the time, synonymous, and shows it to be false. This leaves us with two men with the same father but different names, ending up in different places and conflicting family histories -- one with documented children, the other remembered as unmarried and childless -- without the slightest reason to suggest that they were anything but siblings other than personal preference." Additionally, Boulogne and Bouillon are completely different places. Godfrey/Geoffrey's Boulogne is the one on the north coast of France, now called Boulogne-sur-Mer. The region surrounding it, Boulonnais, became an earldom in the ninth century and was later brought to the crown of England by Maud of Boulogne's marriage to Stephen of Blois.
