Edith May Sandercock, the youngest child of Richard and Mary Ann, was born at Riverton on 16 December, 1880. She would have attended school at Riverton as a girl. At the age of 21 Edith married Andrew Fergusson, son of Peter Fergusson, of Marrabel, on 20 November 1902. The wedding took place at the Sandercock farm north of Riverton, and the witnesses were a C.H. Rex, a farmer friend of Andrew's from Saddleworth, and Marge M. Fergusson, his sister, of Marrabel. Andrew was 32, and the officiating minister on that occasion was the Rev. J.J. Nicholls. It is believed that Andrew was born near Salisbury, north of Adelaide.

Edith and Andrew lived firstly at Marrabel where he continued to farm. Some time later and by 1915, he left farming and bought a store in Marrabel, where he and Edith carried on a mixed business. When this enterprise was sold, the Fergussons moved to Saddleworth, their house on the Burra Road being known as Guernsey Cottage, This was about 1918. The Will of Mary Ann Sandercock, proved in 1926, names Andrew as one of the executors and gives his occupation as labourer. He died two years and five months after his mother-in-law, on 24th October, 1928, aged 58 years.

There were eight children in the Fergusson family, born between 1903 and 1918. The eldest, Agnes Mary Ross, always known as Ross, nursed at the Riverton and Auburn Hospitals, though she had had little or no nursing training. During her service at Auburn Ross nursed her father before his death. She died of a heart complaint aged 29, in 1932, and is buried at Auburn. The third daughter Rita, as a young girl, was said to dislike boys and threatened her mother that should she ever have a brother, she was going to leave home! Unfortunately, many a true word is said in jest. When her mother was carrying her seventh child, Edith herself became ill for some months and Rita and a younger sister were cared for by family members and friends. Rita died at Marrabel in 1916 after complications from measles had set in, and one month later her mother gave birth to a son, Frank.

Edith died in the Riverton Hospital after an illness, on 30 August, 1941, aged 63. She was buried at the Church of England cemetery beside St. Philip's, Belvidere, south of Marrabel, on 1 September, with her husband and daughter Rita. The Fergussons were members of the Church of England and attended St. Philip's when they lived at Marrabel. When the family moved to Saddleworth they worshipped at St. Aidan’s Church near their home at Guernsey Cottage. Edith and Andrew are survived by their three younger daughters Jean, Mrs Stevens, Gwen, Mrs Dickenson, and Midge, Mrs Milde. Madge, the youngest Fergusson child, is a busy Volunteer field worker in the St. John Ambulance Brigade in Adelaide, since her husband Harold retired from their farm at Saddleworth.

Frank Fergusson, the only son of Edith and Andrew, had the gruesome task during World War II of helping to bring home the corpses of Australian servicemen for interment after being killed in action in the islands.
