My Ellen Byrnes (my great great grandmother) was born 15th May 1945 Holborn, London and was listed in the 1851 census at the Christchurch Workhouses Charles Street Mile End New Town with her elder sister Mary Ann b 1840 and elder brother b 1939. I'm guessing she came on the Emma Eugenia as her death cert shows her arriving 1858. According to "The Immigration of Domestic Servants to
Western Australia in the 1850s and 1890s" by Emily Jayne Chambers this ship brought around 130 single women and girls to be domestic servants for the Swan River Colony.
She married Jeremiah McGrath 1862, James Freeman 1868, John Nelson 1882 and John Bryant 1892 and died in 1910 Carnarvon WA.
