Represent a family (yours or a different one), going back to great grandparents. Include first + last name, dates of birth + death, location, portrait, connections. A person is a “node;” each “node” will be a “slide” or “card” or “page”. Start with yourself (your slide); link to each of your parents; link to their parents; and so forth. Links should be “bi-directional,” e.g., users need a way to get back to you from your parents. Your “system” should be extensible for many more generations. You may want to consider marriages as nodes (single slides or pages etc.).
