Wondering did you get all the information I sent, not sure if I did it right. There is Joyce's in Ballynamuddagh, Graddoge, Cloonflynn, Cloghannageeragh, with Brennan's in Graddoge and Weatherfort. The !838 Ordnance Survery Maps can be seen online at
www.mayolibrary.ie/en/LocalStudies. All the towlands are in the same area of Rosslee, but there is no Parish Church. The Local Church is either Mayo Abbey or Carnacon.
I have also found Gerry at the South Mayo Family Research Centre invaluable in my family search, know it costs a few pounds but will worth it.
Let me know if I can be of any further help.
