　　But there was a time in England when there were no last names.A father might have been William,and a mother,Mary,William's wife.A boy's name might have been Fred,son of William.What if another William moved into town?Let's say he was a tailor.He might have been called William the tailor to keep people from confusing the two Williams.The name would then have become William Taylor and his family would have the last name Taylor.This is how family names came to be.
