My Dickinson ancestors came from England and went to Pittsburgh, Pennsylvania, in the 1870s. They lived at 310 Gross Street when the census was taken in 1900. The home was torn down and the land is now the property of West Penn Hospital.
Bloomfield is three miles from downtown Pittsburgh and is sometimes referred to as "Pittsburgh's Little Italy" because of it's large Italian-American population. Every year the neighborhood hosts a large festival celebrating their Italian heritage, appropriately called "Little Italy Days".
This old map was found at http://digital.library.pitt.edu/pittsburgh/ and shows the neighborhood called "Bloomfield".
