O'Brien girls

These girls may be sisters or cousins. Probably born in or near Athenry, County Galway, Ireland. They may have the surname O'Brien or it may be their mother(s) who are surnamed O'Brien. I believe they are the neices of my Grandfather James Joseph O'Brien and my grand-aunt Winnie O'Brien. It's possible that one or more of these girls are the same girls whose photos I have posted here, Winnie OBrien, Norah, and/or Eileen. But they may be someone else entirely. I would like to find them, as they may well be still living and are probably my mother's cousins.
