Recently a small mob from Bristol, UK made their way through Philly to help remind us of , yes, the bloody colonial history of the William Penn family. Jim McNeil dropped some interesting historical gems about the role of certain counter-revolutionary sectors of the quakers in the banking industry, the Penn family's involvement in the slave trade and their general existence as rich, monarchy fetishising, exploiting, capitalist wankers who hardly lived around here anyway (well William anyway). Bristol and Philly as it turns out share a good deal of familiar street names, architecture and other Penn family celebrating landmarks. Be sure and check out their site and a pamphlet that breaks down the whole story!
