who, in the first chapter is charged with "starting it all?"

The first of her ancestors to come to America was a fur-trader and apothecary named Simon Finch.

I maintain that the Ewells started it all, but Jem, who was four years my senior, said it started long before that. He said it began the summer Dill came to us, when Dill first gave us the idea of making Boo Radley come out.

I said if be wanted to take a broad view of the thing, it really began with Andrew Jackson. If General Jackson hadn't run the Creeks up the creek, Simon Finch would never have paddled up the Alabama, and where would we be if he hadn't? We were far too old to settle an argument with a fist-fight, so we consulted Atticus. Our father said we were both right.
