Bernard or Barney Hannan/Hannen/Hannon

I'm looking for a Bernard who married Mary Holloway/Alloway, possibly in Galway or Tipperary.  Four known children — Alice, Mary, Ann and Thomas, plus another three whose names are unknown to me — births either side of 1835 or thereabouts.  Bernard was apparently alive in 1849, but his wife was a widow by 1855.
