I just rec'd a Halberts Book on my surname that was sent to me from my great Uncle in Texas on Durhams... It just list a bunch of Durhams that are alive and (any one can get from any telephone book) and who knows if the history is correct. It is not worth the $35.00 that is charged !! Be Very WARY of this book I have heard that the Halberts has been cited by the Postalservice, under orders from a Federal court to, "cease & desist" a number of times.
