We lived in Germantown until 1955, when things began to change.
There was a large Italian population in Germantown until the postwar years. The composer Vincent Persichetti came from that area. My late mother dated Vince’s cousin.
I went to college just off of 6900 Germantown Ave. in the mid-70s, which was right on the Mt. Airy side of Germantown; it wasn't a bad neighborhood at that time, but I haven't lived in the Philadelphia area since '79, so I'm sure it's gone through a few changes since then--even the college is gone.
