Parents and Grandparents and other family members as far back as you can go.

Who were they? Where did they live? What did they do? What were they like by (a) your own experience, (b) reputation?

Any anecdotes? What they were like from your own memory and interactions? Did they make you laugh? Did they intimidate you? Perhaps both at different times. That tells us about them and you. How do you feel when you recall them? Those feelings are likely to be your best guide to what they were like.

Do you have any paintings, photos, cine or movie of them?
