The first of the brothers to marry, Jack married Ellen Maud Forrest, his childhood sweetheart, at the Springton Church of England on the 29 July 1913 when he was 33. Ellen, known as “Nell”, was the daughter of William and Sarah Forrest (nee Patterson) and she was born on the 29 July 1879.

Jack and Nell made their home at the Sanderston property (purchased by Jack’s  father in1900) and called it Baringa. Their only child, Reginald Forrest Miller (known as Reg) was born on the 11 February 1916.

Jack worked Baringa in conjunction with Pete and Will at Craggy Lea. They were still 
clearing the mallee scrub, breaking in horses, horse shoeing, blacksmithing, and lime burning and from the entries in his daily diary, he was the general go to man. Besides the seasonal ploughing, drilling and harvesting they were cutting chaff for the horses on both properties, milking cows, feeding fowls and pigs.

Having a good water supply from a well on the Saunders Creek enabled them to grow fruit trees, vines and vegetables.  Stock were able to  drink from waterholes in the creek which only occasionally needed scooping to remove the build up of sand.

Over a period of time they were share farming for Mc Gormans, Maxwells and Melrose.

In 1921 Jack purchased an engine from a sale at Bakara for ₤54. Collecting the engine was a two day task, crossing the River Murray at Wongulla with horses and wagon. After mounting the engine on wheels they were able to use it for pumping water and cutting chaff and wood, a great progression from the old horse works.  In 1922 they purchased their first car for ₤155 and in 1927 they purchased a Model T Ford Lorry.

Jack was a Returning Officer for the Cambrai Electoral booth. He would have to wait for the boxes to come in from Wongulla and Black Hill before taking them to Mt Pleasant. On one occasion it was 4 am the next morning when he returned home from Mt Pleasant on horseback.

Jack was a councillor for the District Council of Angas.

Nell was a very good horse women riding side saddle at the Mt Pleasant Show.

With Reg planning to marry in August of 1939,  Jack and Nell purchased Section 73 and part Section 454 in the Hundred of Jutland of 184 acres (adjacent to Craggy Lea) in January 1939 at auction for £7 per acre and named this property The Rockery. After completely rebuilding the house, they moved there prior to Reg’s marriage. Visiting family and friends had always been an important part of their lives.

There is one story about Jack listening to the radio when he first got a wireless. He would turn it off while he was having lunch so that the radio announcer could have his lunch!

Jack kept a daily diary from 1915 until shortly before his death in 1959. These diaries have been a great source of information about their daily lives and his involvement in his community.

Jack died on Christmas day 1959, aged 79 and Nell died just over a year later on 16 January 1961 aged 81.
