In the late 1930s, Ernestine Dew White published GENEALOGY OF SOME OF THE DESCENDANTS OF THOMAS DEW COLONIAL VIRGINIA PIONEER IMMIGRANT. Until recently, this book has been the primary published source for DEW / DUE genealogy. The early results of the DEW Surname DNA Project is calling into question the family connections made by Mrs. White in her book. The Dew Project has identified six genetically unrelated Dew families, two in England and four in the United Stated. In addition, a careful reading of Mrs. White’s book reveals that while she connects a number of early immigrants to North America, with the Dew surname, to Colonel Thomas Dew of Nansemond, Virginia, she cites no documentary evidence to support those connections. She claims John Dewe, d. 1678, Isle of Wight County, was the son of the Colonel, this connection is not supported by the text of the will, as John Dewe’s father is referred to, but not named. The Colonel received no head rights for anyone with the Dew surname. It is not reasonable that members of his family would have immigrated to Virginia, without head rights being granted. The whole purpose of immigration was to acquire land. If you have based your Dew family genealogical research on this book, it is highly likely you have the wrong ancestors. To sort out the various Dew families and correct the many unsupported connections in this surname, more Dew males need to be yDNA test.
