Benjamin is christened HALE, during his childhood years ( as far as the census goes)he is a WHITE, he marries under HALE, and in the first census married in 1891 uses HALE, but its not too hard to see why HALE WHITE came into use by Benjamin and his family. http://www.forum.forest-of-dean.net/index.php?id=33902
