To trace family history of Dwyer family

I am trying to trace the family history of the following,

Denis Dwyer born about 1807 in Tipperary who married Margaret Surname unknown

They had the following children with birth dates approximate,

Honora 1839, William 1843, Mary Agnes 1843, Timothy 1846, Michael 1847, and Peter James 1857.

They left Tipperary in 1858 to travel via Portsmouth to Port Adelaide, South Australia, Australia

on board the ship Storm Cloud. The family religion was Roman Catholic and the occupation of Denis was a farmer.

Any help would be greatly appreciated.

Peter Dwyer.  Email seadragon49@hotmail.com
