How English names are chosen
The English name pool has been replaced almost wholesale twice. The Norman Conquest of 1066 pushed Anglo-Saxon names out of fashion within about a century and a half, and by 1200 the top of the pool belonged to the Germanic names the Norman nobility brought — Henry, Richard, Robert, Walter, William, the last of which has stayed in continuous use for over nine hundred years. The second upheaval was doctrinal: sixteenth- and seventeenth-century Puritans rejected saints' names as Catholic and moved to the Old Testament and to virtue names, giving English Grace, Faith, Hope, Charity, Patience and Temperance. The radical fringe wrote whole sentences into the register — Praise-God Barebone had a son recorded as If-Jesus-Christ-had-not-died-for-thee-thou-hadst-been-damned.
