Several certified genealogists have pointed out that there is nothing in the surviving record that supports the theory that the James de Havilland of this profile ever existed. They maintain that there was only one James de Havilland (father of this profile, a son of Thomas, Sieur de Havilland and husband of Helena de Beauvoir), a merchant of Poole who was mayor four times there (1494, 1498, 1502 and 1506).
