It appears that Thomas Newberry's father, Richard Newberry of Yarcombe, Devon, has been mixed up with a Richard Newburgh, gentleman, of Livingshayes, Silverton, Devon. Douglas Richadson proves that Richard Newburgh was NOT the father of Thomas; see http://archiver.rootsweb.ancestry.com/th/read/GEN-MEDIEVAL/2011-10/1319990601
Richardson concludes: "In summary, contemporary records indicate that the immigrant, [Mr.] Thomas Newberry, of Dorchester, Massachusetts, was the son of Richard Newberry, of Yarcombe, Devon, and his wife, Grace Matthew. Richard Newberry in turn was the son and heir of William Newberry, of Yarcombe, Devon (died 1596), by his wife, Ellen (buried at Yarcombe, Devon 26 June 1609). Thus, the immigrant loses all of his royal ancestry."
