I am researching James Dennis who was born in Ireland in 1811 (father Joseph Dennis mother Ellen Rogers) and died in Parramatta Australia in 1879.

James' movements were:
1842-1844 Australia
1844-1855 England/Ireland (Dublin)
1855-1861 Australia (Deloraine, Tasmania)
1862-1879 Australia (Parramatta, New South Wales)

Family:
1848 married Catherine Hartland Mahon Morgan (daughter of Rev Samuel Malcolm Morgan and Jane Mahon).
Children born in Dublin:
James Tracton Dennis
Samuel Malcolm Morgan Dennis
Joseph Bullen Dennis
Ellen Rogers Lutine Dennis
Children born in Parramatta:
Catherine Emma Hartland Mahon Dennis
Gabriel Edward Blanckley Dennis

James is believed to be a grandson of Lord Tracton.
