I knew that "my" Kirwans were in Killeagh (near Avoca) in Co. Wicklow in 1859-67, and that they were in Foxrock, Co. Dublin, in 1901, but I had been able to trace where else they might have been, until today, when I finally found a birth record for Thomas Kirwan showing that he was born 1892 at Brennanstown, in the District of Killiney, PLU Rathdown, Co. Dublin. My maps show a place called Killiney in the very SE tip of Co. Dublin, but I can't find Brennanstown. Since today's my birthday, I feel lucky enough to ask if any kind soul can locate Brennanstown for me? What parish is it in? Thanks. Chris Kirwan
