Thank you Monica and Lyn, much appreciated. Female passenger list for "La Hogue" arrived in Sydney from the UK on 16 September 1879 lists Mary (31) and Margaret (23) Conway - parents Patrick and Margaret Conway, both could read and write. There is absolutely nothing about Mary in Oz records, despite NSW State Librarians research, however they found numerous "Mary Conway's" listed but none give any lead. Unsure if shipping records are correct and if this Mary Conway is related to Patrick and Margaret, proving quite a mystery. Thanks again.
