Thanks to those who replied. There were two suggestions as follow. I have
not called these numbers as yet.

"Stanford is doing genetic testing of families with two or more members
diagnosed with CD. They were doing free blood draws at the Stanford Celiac
Conference.
  I believe that Dr. Gary Gray is the one heading up this research.  The
phone number for the Celiac Sprue Research Foundation is:  (650)-251-9865.
They may know of other groups doing testing, if you don't qualify for
theirs - it wouldn't hurt to ask. "
and....
"Hi, you could call the Center for Celiac Research in Baltimore to see if
they're still doing the testing for free.  My family had it done last
year.  This is the phone number we called 410.328.6749.  You can ask them
if are still doing the family screenings.  It did take some time to get the
results but they were well worth the wait.
