The National Archives of the U.K. has an on-line database that features historic wills from the 1600s to present day.  For about $7.15, researchers can purchase a will document.  The database is especially useful for obtaining proprietary era wills, including persons who owned property in both Carolina and England, or investors who never actually came to the colony.  Researchers can also obtain eighteenth century wills for Carolinians who returned to England during or after the Revolutionary War.  The site can be searched by date, name, or location.
