Have found a number of children born to James and Bridget Cahill from 1871 to 1884,

James 1871
Arthur 1872
Thomas 1875-1875
Mary 1876
Elizabeth 1884
Patrick 1884

but have been unable to find any marriages for the children or the deaths of James and Bridget, or their children, in the Victorian indexes. Can anyone advised if the family moved interstate?

James and Bridget married in 1870 (bridget nee Ready/Reedy) with their children born in the collingwood/fitzroy/brunswick area
