O'Donnell/Doherty from County Mayo

Looking for family links of O'Donnell's.  My grandfather was Charles O'Donnell born about 1870 to parents Dominick O'Donnell and Mary Doherty.  I believe that they may have lived near Charlestown in County Mayo.  Other family members that I can prove were Patrick, Dominick and Margaret.  All immigrated to Wisconsin in Milwaukee.

I belive another brother may have come over but then moved back to Ireland.

My Grandfather immigrated in 1892.
