Alexander Campbell

Just found this Alf
It would seem that this ship was not the USS independance but a ship of Belfast.

NOW IN PORT, FOR QUEBEC,
To Sail on the 20th June,
The First-class, Coppered and Copper-fastened Ship INDEPENDENCE,
Of Belfast,
692 Tons Register; 1250 Tons Burthen,
ALEXANDER CAMPBELL, Commander.
This fortunate Ship is well known as a regular trader
to Quebec. She will be fitted up, as usual, in the
most comfortable manner, for Second Cabin and Steerage
Passengers, with good wholesome Bread-stuffs and Water
according to Act of Parliament; which, together with
Captain CAMPBELL'S kindness to his Passengers, makes
this Ship a most desirable opportunity for persons
wishing to emigrate.
For Freight or Passage, apply to
SAMUEL McCREA,
General Emigration Office,
37 Waring-street, Belfast.
Belfast, 9th June, 1849.

Looking further I think they called ships like this "Coffin ships" or Famine ships as they took people from Ireland to Canada during the "Potato Famine"

Thanks mate for the information, I was not sure about this ship.
