Family is so difficult...
What I realized recently is that I've been wasting emotional energy by trying to make my transition easier for my family. My therapist put it best, I think.... She said that, "Family sees you as a continuum: the whole of your lifetime. You have to understand that they'll never be able to just see you... they don't have the ability to not think of you as "him," even though, "she," is standing right in front of them."
Your family's perception of you is based on a collection of memories. They've had 35 years of, "him." Their future perception of you will always be a mix of "him" and Jane. The best thing you can possibly do is try and show them how happy you are about your transition. Let them know that you acknowledge their objections (we, of all people, know how important it is to feel validated!) Don't waste your energy by repeatedly explaining yourself as they're just going to keep thinking of ways to convince you that you're delusional. "True Selves," (Mildred Brown) for instance, is a fantastic book ... I bought it for my mom... A few days later, she had dog-eared pages and noted all the things in the book that she saw as not being relevant to me. Love ya, Mom!
Well that same mom of mine gave me a card addressed to, "My Special Daughter," this past Christmas :-) It took three years but my Mom, at least, has come around. Give your family time.... Some can't understand; some won't... after awhile, you'll be able to tell the difference. Forget the ones who won't and stay in touch with the ones that can't; they're the ones who might eventually come around.
I hope this helps
