Mary Costello (1843 -1893) Married Patrick (Patsy) DURACK in Goulburn NSW in 1862. He was from the famous pastoralist family and opened up much of western Queesnsland, Northern Territory and the Kimberly area of Western Australia. Mary was the first white woman to live in the Kimberly at Argytle Station.

Who were her parents? There appear to be several Costello families around Goulburn, Grabben Gullen, Burrowa, Yass areas and I cannot find where she fits in.
Can anyone help please?
