Trying to identify port most likely used by persons leaving Brest or Troyes France to come to NY between 1800-1820. Have located g-g-g-Grandfather BAZILLE GUYOT in one of Filby's books, but it doesn't show a ship's name. Rather it shows him as an alien legally allowed to buy U.S. real estate in 1823, also that he was naturalized as U.S. citizen in 1826. Naturalization paper only shows he came from Troyes met the residency requirements for citizenship. Witness's name doesn't seem to be that of a relative.
Bazille's wife MARY FRANCE LA RUE (LE ROUX) left Brest ca 1810 for NY. Haven't a clue who brought her here if she was 10 yrs old at the time.
Any suggestions where to look next, please??
