What are two names for 15th century hot vampire guys?

I need these for a book. They are two brothers. One is gentile and caring and the other is dark and mischievous. They don't have to be really old fashioned names. (so please no Basil or Langford) l but I need something modern yet tinted with the past (e.g. Damon). I would also need 5 surnames. Thank you for your time, I'd really appreciate it if you answer my question. :)
