When I was in Pittsburgh, my Mom texted me to say that my grandmother's family had lived there, and were recorded there in the 1920 census, and gave me the address. So my friend and I went to look.
And here's where my Nana lived when she was 13:
It's an empty lot. One of the neighbors told me that he remembered the house being torn down about 20 years ago. It's a steep neighborhood, with a brick road. I don't know what it would have looked like in 1920. Still, pretty cool.
