Hit a brick wall. Looking for ancestry of Isabella Alice Addison who arrived Lauceston in 1911 on the'Orsovar'. She later married a William Ritchie. In about 1928 they, their 2 daughters, 3 sons, left Launceston and moved to mainland Australia, settling in Sydney. From what info I have gathered, which isn't much, Isabella's family settled not only in the Launceston area but also in the region of Burnie, Tasmania. Can any one help with this info.
