Based on or tracing descent through the female line.
One of the oddest road trips I ever went on was from the Chicago area to Milwaukee, Wisconsin. I was in high school at the time, and my mother and I were visiting my aunt (my mother’s sister) when it was decided they would drive to the town where they grew up to see what traces of their mutual past endured.
That town was Milwaukee, and my presence on this trip (in which I was stuffed into the back seat and not heard from or spoken to for the duration) was decided upon without my input.
I remember the aggravation of that trip with a bit of good humor today, though it still gets under me.
