Howard DNA testing
There are several Howards who have been tested. Go to this web site and search by name. http://www.ysearch.org/http://www.ysearch.org/
It seems that most of the Howards tested to date are not related or at the very best, extremely distantly related. Maybe Dr. Howard would be willing to submit a DNA sample for a 25 marker test and really back up his claims with scientific proof.
