I am really happy for you.
Child of late '60s myself. Everyone I care about is in the loop: Wife, daughters (3), Aunt, Father, friends, sister, Doctor, obgyn, therapist. Everyone but my younger sister is super supportive. I have not told my son yet as I will not be able to speak to him face to face for another couple of years. I have not told my 96 year old Grandfather either due to my fear of disappointing him. It's kinda sad that I care more about how my Grandfather would react than my father.
I wish you continued support on your path,
Ricki
