Maybe not on open forum but perhaps via a link to a well constructed questionnaire. Your request is non specific, areas such as, relationships, communication, mood,daily living, etc.................., as there are so many combinations and permutations of family members, carer, siblings, extended family, for a start, and how Parkinsons impacts upon them.I have almost done your questions for you!!!
I wish you well but I am not surprised that, as yet, you have not received any replies. There are plenty of posts on this forum where you could glean a fount of information on the subject.
