I am seeking any info of where to locate a business directory of some sort for Bordentown, NJ for the late 1800s thru early 1900s. Specifically, I have a reference form my greta grandfather as follows: "Uncle Josie Newell had sash
& blind factory [windows] on Burlington Street. Had a brother Asher Sisters Hannah Earle, Margt, Elizabeth & Sarah who married Rene Keen".

I have found out that Burlington St. runs from Fieldsboro
(town just south of Bordentown) to Crosswicks Rd. in Bordentown.

Does anyone know how I can find out the name of the business and actual name of the owners of record? Is there anything (old newspaper adveritising images) online anywhere? I have been unable to place this "uncle" in our family and this would help I think.
Also since I have not verified the sisters (possibly married) surnames, I am cautioning anyone who reads this that I would advise taking them with a grain of salt (e.g. Keen, Earle) until then.
