Mcloughlin Family

I need help in finding out about myGrandfather. What I know so far is he was born Martin McLoughlin on Jan. 19, 1873 and baptised Jan, 3, 1874 in Killian Galway Ireland. His birth is registered in Cloonshvina, His parents were Martin and Margaret(Burke) McLoughlin. I know that my great grandfather was a farmer and that he had an older son August. The farm was in Cloonshvina census. I know nothing else about my great grandmother other than she must have died before the 1911 census. Neither she or my great grandfather could read or write. August stayed on the farm but my grandfather Martin immigrated to New York. My grandfather also had a younger brother named Andrew that also immigrated to New York. I would love to have any insight on my relatives.

Thank you to anyone that can help me.
