I'm coming across "4 Knights Court" in early 1800's Philadelphia City directories as the address for my ancestors. What was this? One ancestor to live there was Casper Bransby between 1816 & 1817 (he's not found after 1817) and also Mary Bransby (a washerwoman between 1818 and 1824). Was it related to the court system in Philadelphia? Or just another street? Any help appreciated.
