Janet, there was nothing in the newspapers about Polly Fish except an excerpt from a published story involving fishing. Nor Isaac Fish. However there is a treasure trove of Harry Fish. The first, and only one I looked at told about an accident he was involved with. Check out the following site, (search), use Wayne County and his name and a range of years from 1811 to 1950 like I did. You may find something useful for you.
Edited Didn't check Isaac Fish first, only Polly Fish. Went back and found Isaac .
