If you’re wondering how a man can inherit a dukedom from his distant cousin, take a look at the Duke of Somerset’s family tree (you’ll have to click “show”). The dukes of Somerset bounced all around that tree. The 8th duke was the great-great-great-great-great-grandson of the duke whose title was previously inherited by his distant cousin, the 7th duke. I think. My eyes started glazing over when I tried to figure out what cousin that would make them. Lots of removes. Look up primogeniture and you will understand why only certain males in the tree could inherit the dukedom. It’s fascinating stuff, but so complicated it makes me reluctant to tackle my own family tree, which isn’t nearly as illustrious. I’m pretty sure King Henry VIII is not one of my ancestors!

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!
