McCarthy Family

My grandmother, Catherine McCarthy, was born on April 24, 1881 to John McCarthy (blacksmith) and Bridget Griffin.  She had sisters Margaret (b. 1859), Hannah (b. 1870), Bridget (b. 1872), Julia (b. 1874), Helena (b. 1877), and Honora (b. 1879).  Most of the sisters immigrated to the New York area.  We know she had brothers who we have been told all remained in Ireland.  The names of the potential brothers gleaned from the birth records on RootsIreland are John (b. 1858), Michael (b. 1864), James (b. 1866), and Matthew (b. 1868).   Any help on determining what happened to the brothers would be appreciated.
