Catherine Prendergast/Brickland

Hello 

I'm looking for information regarding my maternal 3rd Great Grandmother Catherine Prendergast who married John Brickland (widower) on 26th Jan 1865 in Philipstown.

They had 2 children Elizabeth born 1865 and Peter 1869, Elizabeth married Bernard Feery and Peter married Mary Moore 

From old newspaper articles it is claimed that Catherine Brickland, Rathdrum, Ballycommon was born in Geashill in 1813 and was between 120 and 123 years old when she died on the 1st February 1934. She is buried in Ballycommon Churchyard and my mother has a photograph of a newspaper article claiming that Catherine was Offaly's oldest woman.

There is one article that states that Catherine or Kitty Prendergast as she was known was at least 110 years old as documents had been found to prove that she was a servant at the Geashill Rectory in the early 1800's.

I have been unable to trace any record of Catherine prior to her marriage to my 3rd Great Grandfather John Brickland.  I would really like to find out if she really was over 100 years old when she died as her death certificate only places her at 94 years old despite all the newspaper articles.
