One of the main objectives of my long weekend in Boston is to research my family history. Usually when you do that kind of research you see familiar visualisation forms: trees. And in this book on a New England ancestral family, I saw trees. But the problem is history is never as neat and clean as we would prefer it to be. Or at least as I would prefer it to be. And this is the tree I discovered for my ancestor George, the guy labelled N-1.

Normally family trees are direct lines of descent. But here the problem is that the current research cannot clearly state who the parents are of George. He can be one of two Georges, one the son of Francis and Tabitha and the other of Timothy and Elizabeth. So instead of a single trunk, we have more of a shrub-like set of parallel branches with lots of leaves.
But what I really liked about this graphic is that, one, it appears to have been made by being typeset on a typewriter instead of some fancy design software (the book was printed in 1984). And then for the researcher like me, the author took care to remove the names of people inconsequential for this particular line of enquiry. It shows the Georges of interest, including the known cousin labelled as C-1, and their parents but omits siblings. It is a very nice touch. (And made my life easier.)
