Gleeson/Gleason Tipperary

I recently discovered that my ggg grandfather, Michael Gleason/Gleeson, was born in Tipperary, Ireland around 1814. He ended up on Wilson, New York. He may have also been listed as living in Newfane or Lockport. All are very near each other. He died in Owasso, Michigan in 1886. His first wife was Bridget Dorsey (1815-1869), whom he married in Ireland. His second wife was Mary Chamberlain, who was born in Ontario, Canada (1833) and died in Nebraska (1919). 

I am trying to find out where Michael and Bridget were from originally. If anyone has any clues, I would  greatly appreciate knowing them.

Thank you,
