Hi I am trying to trace my ancestors back to Ireland and have hit a brick wall.  The ones I know about are my great grandmother, Honora (Nora) Prendergast, John Prendergast, Annie Prendergast and possibly Thomas Prendergast.  All settled in the Braddock, North Braddock  area of Pa.  JOhn was the first in 1878 we think. We know he and  nora and ann were siblings from a first marraige.  There were several other children and then the father remarried and had several more.  We do know that he was a postmaster of his area and we're pretty sure it was mayo, possibly Claremorris but that's the problem. No records exist about the homeland.  If there are any other Prendergasts out of mayo who have done research on the family I would be very grateful for any information
