I am a descendent of a James Colclough. He arrived as a convict to NSW in 1828. He gained his TOL in 1844, the year he married another convict, Margaret Kane and his COF in 1845.They had 9 children (5m 4f)and eventually settled in in the far west of NSW and then to Narrabri. He died in in 1894. He was the last of the "Colclough" convicts in NSW and I think Australia.
Eventually the male line of this branch died out in 1960 when the last of the Colclough males passed away.
The many spelling/pronunciation variations area nightmare for anyone tracing this name but I found the 2 most common to be were "Cokely" for the Irish Branch and "Cocluff" for the English branch.
Information that I have found that may help others tracing their respective Colcloughs is:- Around the 1860, a couple of "CoCluff" brothers arrive in Queensland with their families and were members of the Constabulary. A great many of the present day Colcloughs in Queensland descend from them
Around 1874 a family of "Cocluffs" settled in country Victoria as farmers and descendents still farm at this present time
In 1913 another family of "Cocluffs" settled in central NSW around Canowindra and I believe are still there to this day.
In the early 1800, there were a number of Coclough in South Australia working as servants, 4 convicts in NSW and 3 convicts in Tasmania. One Charles Colclough died in 1844 aged 45 but I can find no info on him at all.
