‘Squirrel Town‘ was a low income section of town roughly bounded between South Adams & South Alves Streets and Clay & Dixon Streets. The earliest mention I can find is 1910, with the killing of Ulysses Watson. The article mentions the killing took place in “Squirrel Town” a negro settlement in the southwestern portion of the city.
A 1982 article about Anthony Brooks states: “Where he came from” was what Brooks calls a pocket of poverty on South Ingram Street, also known in the late 1940’s as “Squirrel Town.”
