I'm certainly sorry to trouble one of our group's most devoted members. But "Boudicca" is the spelling used in Peter Salway's Roman Britain, as well as in the article I was citing to (and in the title of this thread), so that's what I would tend to follow. I would certainly concede that "Boadicea" has a Victorian grandiloquence about it that makes it a name more suitable for poets, sculptors, and writers of Sir Winston's genius to cast their spells with. Would Boudicca/Boadicea have been "bodacious"? Hmm. That's one I shall have to think on for a while.
