I have posted some NYC directory listings of Ficketts and Thomes in the early 1800s. When the British burned their Kittery shipyard in the War of 1812, two sons of Jonathan Fickett and Elizabeth Crockett, Asa and Samuel, moved to NYC and eventually had ashipyard there (which built the S.S. Savannah). A sister of Asa and Samuel, Phebe, married Samuel Thomes. Their children show up in the NYC directory listings also. By the 1820s the shipyard at Corlear's Hook was called 'Fickett & Thomes Shipyard'.
This doesn't answer your question, but it maygive you leads.
I believe Francis Fickett was a son of Asa. He usually gets credit for the Savannah, but was probably too young at the time. He became an Alderman of NYC.
