Aphra became a name used occasionally by 17th century English Puritans and their descendants. It was coined when they misread Biblical verse Micah 1-10 in the King James Bible (“in the house of Aphrah roll thyself in the dust”). Many Puritan parents took Aphrah to be a personal name, rather than a word meaning “dust.”From http://www.geocities.com/edgarbook/names/az/aphra.html
