Thanks for the info. I had some of the trips but not all. The 1909 trip shows he went out for a season there before returning to Scotland in 1910. He later went out for good in 1910 with his two brothers.
A Boer War veteran of the Black Watch, he came back to Scotland and served with the Cameronians if the First War and was invalided back to the Falklands in 1917.
The archive in the Falkands has been very helpful and they may have info on your forbears.
Good luck and thanks
