Samuel Gray arrived in South Australia on 6 September 1851, on the 'Alliance'. In 1854 he married Betsy Heading of Payneham. In 1876 he purchased a 6-acre block of land at Sydenham, bordered by the River Torrens to the north and Crowle Road to the south.

Samuel, who was a member of the Campbelltown Council in 1887, passed the property to his eldest son Isaac in 1888.

The property subsequently passed to Isaac's son, Sidney Ernest Gray, and ultimately to Sidney's son, Arnold Gray. The property remained in the Gray family for over 100 years before it was sold. The Paradise Community Church now owns it.

Sidney's brother, George, also had a market garden at Paradise, - opposite the Campbelltown Memorial Oval on Lower North East Road.

Sidney and Arnold were keen local sportsmen. Sidney won the bowling prize with the Paradise Cricket Club in the 1906/7 season and was vice-captain of the Club the following year. Arnold excelled at cricket at Paradise as wicket keeper and batsman and was good enough to be invited to train with the East Torrens District Cricket Club. He was also a very good footballer and played with the local Glenroy Football Club. He won a number of club and East Torrens Football Association best and fairest awards and received an invitation to train with the Norwood Football Club. Unfortunately, the demands of market gardening prevented Arnold from accepting either offer.

Most members of the Gray family are buried at Payneham.
