ROMAN DEBAUCHERY FUN FACT TIME!!!
And you know what is especially fun about this Fun Fact?
IT'S ABOUT ME!!!
A few days ago, she calls me with a somewhat strange question: "Did Constantine the Great ever spend time in Britain?" This is strange for her, as she could normally care less about Roman history, but when she needs to know things about it, she naturally calls me. I answered yes, he did spend time in Britain. "HOLY CRAP!" she yells into the phone. "WE'RE RELATED TO CONSTANTINE THE GREAT!"
Admittedly, I was skeptical. I knew these ancestry databases could be thorough, and some people are able to trace their families back almost a thousand years. But Constantine? Anything that far back seemed impossible. The centuries following Rome's fall were called the Dark Ages for a reason, after all.
I asked her to show me the site. She provided me with some screenshots of her search, which I included below with some arrows clarifying the line in question:
It's also worth noting that the timeline gets Constantine's birth year wrong, too, and shows his father marrying his mother a year after his birth, although this by itself is not disqualifying.
But that's not all...
Of course, Geoffrey seems a little confused about his Constantines as well. He refers to Constantine III as Constantine, or Custennin, the Second of Britain, and it is suggested that he may have mixed up the Roman usurper with a British king of Dumnonia. (Jamie Delano wrote a very diverting story about this king in the DC/Vertigo series Hellblazer, presenting him as an early ancestor of John Constantine.)
I suspect there was a legitimizing factor for a British/English king who could claim to be descended from Roman imperial blood, leading early kings to follow (and invent) their own tenuous ancestral connections to famous Caesars.
Or vice versa.
