Geoffrey from A Duke for Diana is partly inspired by an actual duke who was responsible for countless canals in England: the Duke of Bridgewater (I kid you not—that was his name). He was dubbed the “Canal Duke” because he had so many of them built or expanded. Interestingly, he never married. He was engaged to the Dowager Duchess of Hamilton (the former Elizabeth Gunning, noted society beauty), but broke it off. The Dowager Duchess went on to become the wife of a marquess who became the Duke of Argyll (so she was married to two dukes and engaged to one), and she also gave birth to four dukes (only two dukedoms, though). Thus, SHE is the inspiration for Lydia, the mother of the three dukes in the Duke Dynasty series. Hey, I take my inspiration where I find it!
