Genealogy

A family tree kept at home rather than on someone's platform. People, unions and places go into a base of your own; the tree draws itself upward from whoever you put at the root — Sosa 1 — parents above, grandparents above them, each card with a portrait, a name, two dates, and a little cross to open the generation beyond. Fold, add a generation, show everything: fifteen people on screen out of two hundred and sixty-six in the base, four generations of eight. A second marriage hangs off its card as a small note — widow, the year, the other name. A list and an archive sit beside the tree, and a search box finds anyone by name.

The Sosa numbering is the old genealogists' one: you are 1, your father 2, your mother 3, and each parent is twice their child. Nothing else is invented; the tree only shows what you wrote down.
