Not really, Wade, he was my great grandfather, and he was always referred to by "Denus" by all I knew, including Gerry. I think they just went along with the spelling that had become accepted over the years. Kind of like Balfa and Bolfa.
The patron saint of Paris, France is St Denis (Dyonisius).
My sister's name is Denise. In French, these are the correct spellings of both names. But whether it's Dennis, Denis or Denus, we all know who he was. A great- grandfather to be poud of.
Thanks for the info and I'm looking forward to the film.
