I am biased when it comes to
Julius because I am so in love with the name
Julian. I really prefer
Julian - it has a much more pleasant sound imo. To me there is only one
Julius & that's
Julius Caesar. As for mns I would probably go for something that softens
Julius somewhat.
Julius Alfred seems like the best option from your list. The only other alternative I can think of now is
Julius Everett.
