Actually,..According to "Nauset and The World..
Thomas2 Vincent, (William 1), b. 15 Sept. 1656; res. E. and is called a gunsmith (1689) and a locksmith (1707) ; prob. rem. to Norwich, Conn. bef. 1707, where his wife's family resided. He m. Sarah Post, dau. of Thomas and Mary (Andrews) Post of Norwich abt. 1676. She was b. Nov. 1657 and was living in 1746 (Norwich Land Rec. X, 16). He prob. returned to E. and adm. of his est. was granted 4 Mch. 1740, and the inventory of his est. showed property to value of £240-4-0.
I am not sure if he would have owned his own company or worked for a 'smith in the area as Norwich was Founded around 1659
