 
This collection of articles on medieval and Renaissance names is intended to help historical re-creators to choose authentic names. These articles were gathered from various places, and some of them appear elsewhere. In all cases, the copyright on each article belongs to its authors.
For frequent users, we offer a compact index; but please read the following introduction at least once.
To be honest, it isn't that easy. at least not if you truly want an authentic name. Few history books reproduce names in the exact forms that were recorded in period documents. Most of the names are modernized and anglicized, both in spelling and form. Depending on just how authentic you want your name to be, you may or may not decide to worry about these details; this collection of articles assumes that you want your name to be as authentic as possible.
Many people in the Society have written articles to help you choose an
authentic name.  Answers to some common general questions can be found
in the Academy of Saint Gabriel  
Client's Guide. 
The Problem Names Project
Some names that many people think of as common to the Middle Ages or 
Renaissance are either purely modern or otherwise problematic. For 
example, some names which were used in one medieval culture are now 
mistakenly believed to have been used in others. Other medieval names 
are mispronounced, or thought to be feminine names when they were 
only masculine. If there are common misconceptions about the pre-1600 
use of a name, it may be a "Problem Name".  Pointing out these
misconceptions is the purpose of the
Problem Names
Project of the Academy of S. Gabriel. It includes a couple
dozen articles on specific names that are commonly misused by
re-creationists.
