I am looking for descendants of my father's first cousin Patrick F McMahon (b 26 Feb 1872, Limerick City, Co Limerick, Ireland) who married Catherine Virginia Davis, known as Virginia, (b 14 July 1876, Jersey City, NJ, USA). They were married 23 Nov 1904 in Jersey City. The family used the spelling MacMahon in Ireland, but seemed to have changed it to McMahon in the USA. Patrick was a foreman on the railroad.
They had three children Francis (b ~1905), Bertrand or Bertram (b ~1911) and Elizabeth (b ~1914).
They lived up to at least 1930 at 221 Porter Avenue, Bergenfield, Bergen, NJ, but moved later to 28 East Nauraushaun Avenue, Pearl River, Rockland, NY.
Four of Patrick's siblings Mary Susan, Helena, Joseph Alphonsus and Terence James also settled in the NY/NJ area.
