Hi Brenda. If you are still wanting the passenger list fo New York Packet, here it is. My ancestors Robert and Ann Bodle/Bodel/Boodle were on this ship in 1841, with their two sons, including my Great grandfather William George Bodle, aged 1.5 years.
You can find other ships arriving in NSW at this site, too.
