The building at 42 Bank Street in New London was built in 1833 in the hope that it might be used as a federal customs house. In the end the building, which resembles a Federal and Greek Revival-style row house, became home to the Whaling Bank. The bank, the third oldest in New London, was founded in 1833 by a group of whaling merchants that included Joseph Lawrence. It became the National Whaling Bank in 1864 and remained in existence until 1943.

I found this link after researching the ancestry of Francis Mourilyan Butler,the former owner of Carswell Manor in Buckland, England(Butler bought the manor from architect William Niven who was the grand father of actor David Niven). Butler married Josephine Brown Lawrence in Manhattan 1902. Josephine was described as an heiress in the wiki entry for Carswell manor – I have edited in her links to the Whaling family mentioned here.
