Hi
i think we share Patrick Smyth and Catherine Bones as ancestors in my case through their son Peter Smyth baptised 18th October 1850 at St Mary's Drogheda. on a recent trip to Dublin i also located baptisms for John 2/4/1860, Nich 17/8/1862 Francis/Frank 23/4/1865, James or Jas on the 2/11/1868 all of these were in Stalmullen. the Meath heritage centre might be able to provide you with more information to push the family backwards, perhaps a marriage for Patrick and Catherine.
