Sometimes just Googling a topic will bring up a very helpful piece of information
regarding your inquiry which will enhance what you know about a family business.
Naturally, researchers want details of a specific business, but there are also
details to be learned of the general nature of the business which are important
too.

In regard to the fishing business, there is an article >from "Fortune Magazine"
which discusses the fishing business in 1935 and the early 20th Century:

It gives much insight into the nature of the ups and downs of the business and its
prognosis for the future.

In addition, there is a site "I Am Provincetown" which provides info on the
