From her obituary, Mary came to Australia (Sydney) in 1852. In 1858 her two brothers, Ralph and Thomas came here on Herald of the Morning, assisted immigrants. Passenger list indicates two sisters Mary & Eliza were living in Sydney. It's thought they sponsored their brothers. One of the Burke brothers, I think, Ralph settled in the Taree area.
Unfortunately, Mary & Eliza Burke are names too common. They iriginally came from Killalon, County Meath, Ireland.
Can anyone assist?
