The abstract to this paper reads:
“Multiple washovers laid down between 2200 and 900 cal
yr B.P. suggest an interval of frequent intense hurricane
landfalls in the region.”
The text states:
“Numerous sand layers preserved in this core are tentatively
dated to 2200–900 cal yr B.P. and pre-2800 cal yr B.P.
Unfortunately, they do not have specific dates for specific
overwash events. It might be interesting to see if any of the
sands beds within the lowermost part of this interval just
above its 2200 cal yr BP start differs noticeably from all of
the others in thickness, grain size, or some other physical

In it, there is listed the citation of a paper that has been
submitted for publication. It is:

submitted, Sedimentary evidence of hurricane-induced coastal
flooding in southeastern New England over the last two
millennia: Geophysical Research Letters.
Maybe this papers might have some answers.
Also, if there is enough interest, someone in your
"asteroid lunch" group could email Dr. Jeffrey P. Donnelly
