I find it strange that 'stackchips' has previously posted several questions, probably wanting honest, helpful answers, but yet posted an unhelpful answer to someone elses question.
Second I do have to agree that there really has never been substantial evidence diabetes is solely or definately hereditary. (To my knowledge of course). I have type 1 and NO ONE in either my maternal or paternal sides have ever had type 1 diabetes. So in my case, doctors say it was not hereditary, but most likely due to an illness suffered when I was a child causing antibodies to be out of whack.
So I have to say it could be the luck of the draw. Don't let fear of diabetes keep you from having children. Children are a blessing no matter shape, size, or ailment.
Good luck and best wishes to you and your new wife.
