The answers are yes, and yes. I am back and I have begun my new job. Finally, back into archaeology.
Now, I have been monitoring this thread for a while, and think that Mary Ann may be a good fit for EBSI's site. It was used, I believe, as a charcoal manufactory after its occupation. The other option is, of course, Allaire. It did run for quite a while. The problem I see with all of these however, is that even if the informant is in his 80s, then we are only looking into the 1920s or 1930s; and, many of the operations for blast-furnaces and forges were already defunct, or quickly heading that way. The iron from Pennsylvania far eclipsed bog iron by the late 1860/1870s.
A final note on the whole 1833 Gordon discussion... these historic maps were somewhat accurate, they would at least get you in the ballpark. After all, they were not GPS or GIS crafted, but were relied upon by those who bought the gazetteers and atlases. So, they did need some measure of accuracy. Will they get you within 3 meters of a site? Who knows... But, they will at least tell you what area to begin looking in.
A note on the other geographical question... My information for Red Oak Grove comes not only from gazetteers, but also from the US Postal service (and the actual application filed to open an office) and original deed, and county record research. The office change locations from Burlington County to Ocean County. THAT is the change in location, not a cartographical change, but a shift in the central locus of the "town". This type of change, though an exercise in symantics, is important to note because it could indicate a shift in traffic, or importance of one location over another.
Since we still know so very little about Red Oak Grove (i.e. the type of settlement, population statistics, proper boundaries, etc...) it is more important to show that the village spanned the Ocean/Burlington county borders than to simply pick one simple location for the town. This is why I put that information into the article. ROG was a geographically large settlement that was possibly amorphous, and atypical. Some other developments that spanned borders like this were Wheatland (over 1600 acres of development that went belly-up), and the later Red Oak Park (founded on the vestiges of Wheatland/Pasadena).
Finally, I would like to say that it is good to be back, and I hope to be researching again soon. Perhaps, I will focus more on Burlington-County for fleshing this area out, as I have nearly exhausted Ocean County's resources (excepting, perhaps a major scavenging of Monmouth and Ocean deeds).
Hope everyone is well,
