You are very knowledgeable, Martha!  Just another query.  I’m a carrier of CAH and so is my husband.  Does that mean one of my parents, grandparents, great-grandparents, etc, was also a carrier (and same on my husband’s side)?  As we don’t know of any other SWCAH people in our family, does that mean it’s gone through a few generations where they have all been just carriers on both sides of our families?
