Need info on Bernard Pierce born 1864

I am searching for info on my great grandfather Bernard Pierce.  He was born in Galway Oct. 1, 1864 and went to the United States (Boston) in 1882.  He married Bridget Taylor from County Sligo in the United States in 1885.  They had 10 children (Bernard, Winafred, Mary Verecunda, Mary F. , Joseph Henry, George Francis,  Leo Thomas, Bertha, Matthew Christopher, Matthew Bernard.  I was told he was born in Galway Bay but I do not believe there was a town named Galway Bay so the whereabouts of his birth are unsure.
