My girlfriend has a conference in Philadelphia over this weekend. In her free time, we are taking in Valley Forge [Sat] and the Philly Historic District around Independence Park [Tues]. The rest of the time, I'm on my own.
My plan for Monday was to research both of our families at the PA Historical Society. There was a slight glitch in that plan, the PHS library is closed on Mondays! Backup plan, the Free Library of Philadelphia. The library has a genealogy department, so may offer some of the sources I need to check.
When you go on a research trip, check the hours of local repositories and have a backup plan!
