I lived there in the '60s and 70s and I've never heard it referred to as Beantown...

From Connor Creek into GPP south of Jefferson was a swamp. The Fox Creek canal, now along Alter Rd. was always there before Europeans even arrived, but it did have a more meandering course originally. The canal around Harbor Island was part of the original path it took. I can see the attraction to keeping that natural canal-front property as the area developed.

You can see how it changed between 1878 and 1904.
