I have tried to include books on different languages, but of course, most languages have been skipped. If you have more specific interests, please feel free to contact me again. Your local pursuivant should have gotten a copy in August 1990 with the Rules for Submission. This list was compiled a couple years ago, and there are many books that I would like to add to it. I will probably revise and update it sometime soon.
Suggestions are welcome.
When you document a name, the most important thing is to have a dated citation of the use of the name before 1600. Keep in mind that many modern authors will translate names into modern English. For example, the Penguin translations of the Icelandic sagas are an excellent source for learning how Icelandic names worked. However, the translators have anglicized most of the names. If you want to find the proper medieval form of the name, consult a more scholarly reference, or contact a senior herald, who can probably point you to someone in the College of Arms who can help you.
