WE know that Ralph and William Sprague were the sons of Edward Sprague, fuller, and his wife Christian, of Upwey, county Dorset, England, as they are mentioned in his will, dated 16 June 1614. He had altogether six children, three of whom came to America. Of these three, only Ralph and William concern us.
