The current book I'm working on is set in England in the late 9th century AD. I was find it difficult to get myself moving because I just couldn't get my characters any names. Then I found the Domesday Book on line. I selected a couple of towns and used the names from those towns to get me going. The was the first time in history that people really started to get last names that stuck. As there weren't that many first names, the big wigs needed to give the peasants last names so they could keep better track to them. Makes it easier for tax collecting!
Where do you get your character's names?
