Looking for any information for Patrick Mullane & Margaret Mullane (born Murphy)

Hi Everyone,

                   I am looking for any information for a Patrick Mullane who married a Margaret Murphy.

Sadly the only information i have is that their son John Mullane, was born in 1792, in Newcastle, Limerick, Ireland..

                 John went on and married, Bridget Barry in 1835, in Ard, Limerick, Ireland, had several children.

                In 1841, he emmigrated to Australia on the ship "Forth", with his wife and two children.

 So, you can see i have little information, so if anyone can assist i would greatly appreciate it. I am interested in the parents of John Mullane, and in particular their dates of birth and death, and any siblings that John may have had.

  Regards, Bigbob
