Another place you might look is in the collections from the South
Street Seaport, moved to the New York State Museum in Albany, NY
recently. The Quakers (one a Mayor of New York Walter Bowne) began the
"mail packet" ship lines that competed in crossing the Atlantic on
regular schedules, mostly to Liverpool, England, on two week
schedules. They exchanged cotton and mail with Liverpool, some taking
up residence there also.

They also stopped in at Setauket, NY I've read, once having
shipbuilders of renown there and the adjoining harbor which became
Port Jefferson from "Drowned Meadow" reportedly where John Paul Jones
shot two British Navy officers on the "Nehantic" please if anyone
knows more about that let me know)

Recently I worked near the Clove Road Quaker Meeting House near
Woodbury, NY (the one near Harridan, NY not Woodbury on Long Island,
though in Westbury there were/are many Quakers, their cemetery on
Houston Street ("howston") in NYC's Bowery, transferred mid 19th
century there and to what became Prospect Park in Brooklyn on the
Coney Island Road) but as far as I know no archaeology has been done
there.
