Maybe one way to fix the "how am I related to this person, again?" problem is with a graph that's really easy to display succinctly. Here are some ideas:
All of the above drawings represent my dad's mom's dad's dad's mom. The first three are nice because they vary in two dimensions (and seem easy to grasp at a glance). The last two are nice because they have a uniform height.
1. Without color, the gender of the person on the left is ambiguous (unless you know it's you).
2. Could you extend this to show cousin/sibling relationships? Maybe something like:
A: My mom's mom's sister's child.
B: My dad's brother's son (here the lines on the left without dots indicate gender)
C: My mom's mom's sibling (gender is ambiguous unless a dot-less left line was included on the leaf dots).
After drawing the MMFMMF one from above, I thought, "How about a series of interlocking Ms and Ws?"
What do you think?
