Looking for my grandfather

My name is Julie and I live in the United States.  I am looking for my grandfather Michael H. Burns or Byrnes. He was born in 1874 and I am told he came from Droheda. He immigrated to the US (though I am not sure when) He would have been a young man.  After leaving Ellis Island he came to Grand Rapids, Michigan.  Michael married Margaret Gertrude Ebbit in 1903. In 1939 Michael died.  I know this is very sketchy information but at this point it is all I have.  Any help would be most appreciated.
