I am a little nervous about this whole thing but I need to share my discoveries so that they are not lost to the world, especially not to those who one day may start searching. Jane HYDER came to Australia in 1867 as one of Miss Rye's immigrants. You can read about Maria Susan Rye here http://www.nationalarchives.gov.uk/nra/lists/GB-800819-Rye.htm
as well as on many other sites. Jane Hyder was about 22 years old when she arrived in Melbourne (Port Phillip) and was employed by a local person in Sandridge, the original name for Port Melbourne. She would have been well educated as she grew up in the Royal Hibernian Military School in Dublin where her father was Quartermaster Sergeant.
At some stage she found herself in New South Wales where she married Michael Murray in 1868. Here is a link to a notice of the marriage in a Limerick newspaper of the time.

My discoveries follow a pattern of accidental surprises mainly from everyone's good friend Mr Google and this was one of many.
Michael and Jane had three children in New South Wales, Catherine J born 1869 in Patrick Plains, Mary Edith born in 1871 in Musswellbrook, and Thomas William born in 1873 Murrurundi.

Thomas John Hyder was one of Jane's younger brothers. He topped the class in his final year at the Royal Hibernian Military School which won him a handsome prize and training as a monitor to teach in the school. He gave up this appointment when he was just seventeen to join his sister and her family in Australia in October 1874. He had further training here as a teacher and was sent to a village called Stroud where he came face to face with his future wife, Amelia Laman.
For some reason though, Michael and Jane saw a different future for themselves and their children. They were on their way back to Ireland by April 1876 but not before Jane, being the legal guardian of Thomas, inserted a notice in the newspaper cautioning ministers and registrars not to marry her brother, as he was under age. Thomas remained and found his calling in the Anglican Church. He married Amelia and they had seven children but it was not a fairytale ending.

Strength and resilience seem to have blessed the Hyder women. Jane was nearly six months pregnant when she began the journey home to Dublin, pregnant with twins. The twins, Richard Michael and Ellen Maud, were born in Dublin only a few weeks after the family arrived back in their homeland. There was no rest for Jane as soon the family was on the move again, either by the end of 1876 or early in 1877.
They settled in Whitby, Ontario but Jane was without her new little daughter who remained in England with one of Jane's sisters. More children were born in Canada but leaving behind her newborn daughter can only have been slightly less heart wrenching that losing her two sons to scarlet fever in 1878.
