ClarkEnglish Means "cleric" or "scribe", from Old English clerec meaning "priest", ultimately from Latin clericus. A famous bearer was William Clark (1770-1838), an explorer of the west of North America.
YorkEnglish From the name of the English city of York, which was originally called Eburacon (Latinized as Eboracum), meaning "yew" in Brythonic. In the Anglo-Saxon period it was corrupted to Eoforwic, based on Old English eofor "boar" and wic "village". This was rendered as Jórvík by the Vikings and eventually reduced to York.
