Looking for information on a convict who was transported to Tasmania in 1837.

Information:

Daniel Magrath (born 1798 - 1808 Limerick, Ireland)
married on the 26 February 1829 or 1 March 1829 Wath upon Dearne, York to Mary Wright (possiby the daughter of Thomas Wright and Mary Samadine, born Rotherham? c.1808)

Children
George Wright Magrath baptised circa 24 January 1830.
Mary Scamadine Magrath baptised circa 12 July 1832 (it is believed she died in infancy or as a toddler between 1832 - 1835)
Thomas Henry Magrath born circa 1835, Rotherham, York

Daniel was transported at the Warwick Assize in 1835 for forgery. He was a butler and gentlemans servant at the time.
After his arrest Mary moved back to Rotherham. Daniel was in prison when Thomas was born.

In 1839 Mary and the two boys were given free passage to Tasmania, Australia to join Daniel. By this time Daniel had proven himself to be honest and reliable.

Any Information on the family (marriage or baptism certificate transcript) or Daniel and Mary's parents greatly appreciated.

I thank you in advance for any assistance you may be able to give us.
