George BAILEY in South Australia 1837

Hi all
George BAILEY arrived in South Australia in 1837. The name of his wife and child are unknown. George was later remarried to Elizabeth HARVEY on 18 Feb 1843 at Adelaide, South Australia. He was a gardener and died 17 Jan 1870 and is buried at Echunga, Adelaide. I am a descendant of George and his first wife. They had a son James or William who married my gggrandmother Sarah Ann SPARROW. They had Sarah Ann Mortimer BAILEY who married Herbert HORNSBY in 1907 at St Arnaud, Victoria, Australia. I would appreciate any enlightening information. Kindest Regards
