Just did a quick search on:
http://www.familysearch.org/Eng/Search/frameset_search.asp for you, and came back with the following results:
1 Hugh CREANY
Christening 28 May 1801 Magheralin, Down, Ireland
father Patrick CREANY
2 Hugh CREANY b about 1801 Magheralin, Down, Ireland
father Patrick CREANY
3 Marriage record:
07 Sep 1829, Penfield, Charlotte, New Brunswick
Hugh CRANEY (b 1803, Ireland) m Elizabeth MEALY
Hugh CRANEY d 15 May 1868
There is a slight difference in surname spelling, but the christening date is very close. (Perhaps the date you had was his birth?)
It looks possible that his father's name was Patrick (a very popular Irish name!)
