There have been a few changes in the neighbourhood over time, but most streets still have their original name while some were changed once or twice.

One notable exception is current-day Geneva Avenue in the neighbourhood.

In 1858, it was Locust Street.
By 1899, it was Gildersleeve Avenue.
By 1913, it was Geneva Street.
…and sometime after 1924, it became Geneva Avenue which we know and love today.
