The Creole was a "veteran of 40 Atlantic crossings...a well-known ship on
both sides of the Atlantic--easily identified in port with the unusual
figurehead of a Creole Indian in full head-dress and war-livery."
On another voyage, "in December 1848, she was bound for Philadelphia out of
Londonderry...a vicious electric storm surrounded her and she was hit full
on by a streak of lightning...lost two-thirds of her sails, main and mizzen
masts, and limped back into Cork, on December 7th, 1848, after three weeks
at sea...all the crew and 221 emigrant passengers were safe."

There are 17 references to "New Orleans" in this title. One of the most interesting was listed on p. 260 in the form of a review of the title, about Henry Ford's father.....and a voyage from Cork.
"This is a splendid book, written in fresh and accessible way, which will grip anyone with the most superficial interest in the FAmine years.... While not avoiding the narratives of the most famous emigrants in these years (Henry Ford's father from Cork and President J. F. Kennedy's great- grandfather from Wexford) he concentrates on lesser-known stories: a good example is the Wexford parish priest who led eighteen families across the Atlantic to New Orleans and then up the Mississippi to found the town of Wexford, Iowa." - Frank McLynn, The Irish TimesWould it be too difficult to travel onwards and up the Mississippi River?
Did Irish families stay on in Louisiana? I believe so :)
