I'm researching the Gallahar and Tonga family line. Henry Gallahar(b.1879 d. 1952) came from Hobart to Tonga where he met and married Malia Tonga (b. about 1880). I'm not sure how many kids they had, but one of them was Tasman/Tasmania/Tasi Henry Millhouse Gallahar (b.1910). Tasmania married Meliame Fatai Finau Tonga?
If any of these names sound familiar to you please contact me.
