Test Case: Philadelphia (2nd Street west to 6th Street; Spruce Street south to Christian Street)

In Harry Boonin's book "The Jewish Quarter of Philadelphia, A History and Guide 1881-1930", Mr. Boonin mentions that Eastern European Jews settled in several locations in Philadelphia, but most settled in the area bounded by Spruce, Christian, 2nd and 6th Streets. This same area was also settled by several other immigrant groups.

Harry Boonin's book is out of print, but it can still be viewed and purchased at the gift shop of the National Museum of American Jewish History on 5th and Market Streets. (I have no financial interests in the book, and I do have Mr. Boonin's approval to refer to his book.)

Looking at a modern day map of the area, this rectangle includes the following streets (in all cases, both sides of the street):

This is according to the 2013 map. Adjustments have to be made for different names and different boundaries in 1900 Philadelphia.

These streets and blocks will be the main focus of our test case in using the US census data.

In 1900, Fitzwater Street was named German Street for part of the way, and Davis Street further east.

In 1900, Cypress Street (or Delancy Street) was Powell Street, between 5th and 6th Street.

In 1900, Phillip and American Streets might have been Lavant Street between 2nd and 3rd Streets, and between Gaskill and Monroe Streets.

In 1900, Fulton Street might have been Harmony Street.

In 1900, Kenilworth was called Almond Street.

In 1900, Addison might have been Powell Street and Brickley Street.

In 1900, Delancy might have been Landis Street.
