Naming your character is one of the most important parts of ren-faire-ing. Not only do you have to take into account the time period, but also the nationality. Sure, you could always just call yourself “John” But if you want a more unique, suitable name and/or surname, you’ve got to do a bit of research.
Note: this is for historically accurate naming. If you’re set on a “fantasy-based” name like Tanloramth or Meristanya or Mindumesya or Avulalith, then we won’t stop you. Maybe.
The following sites are great for all your historical naming needs.
The Medieval Names Archive has lots and lots of links to other naming sites. Literally dozens. Maybe Hundreds. More than twenty nationalities, divided up by time period. You’ll probably be able to find something here. It also has sources for naming Things, such as “places, ships, buildings, clans, military units, and orders of chivalry.” Worth diving into.
If the Medieval Names Archive is too huge and daunting, here are some smaller-scale options.
