Three brothers left Molong the town of their birth in order to find work. John Peter (Jack) McArdle left for Broken Hill in the later half of 1905 "to follow mining pursuits" according to a newspaper article. His brother Victor (Vic) Vincent McArdle arrived in Broken Hill about April 1906. Vic sent a postcard of a dust storm from Broken Hill to his brother Maurice Michael (Bob) McArdle who was still in Molong.

The three brothers worked in Broken Hill and sent money home to their father, Peter McArdle, to help pay for the tuition of their sister, Kathleen (Kittie) at Perthville Convent School near Bathurst. By December, Jack had fallen ill. He sent a letter to his brother, Pat, who was still in Molong saying he hoped Kittie was doing well. By Christmas evening Jack had contracted Typhoid and he was dead in five days. His funeral notice was placed in the newspaper by the AWU and he was buried in Broken Hill.

Vic worked for BHP as a trucker for 15 months from January 1907 to April 1908 when he left of his own accord to work on the property "Burta" as a blacksmith. from 1908 to 1912 Burta was owned and managed by Charles Robert Murphy and by 1914 Arthur Crossing was listed as the station owner. Bob had arrived some time during 1906 and also worked for BHP as a trucker until he went to work on Burta with Vic.

Bob again went to work for BHP in 1911. By 1912 Maurice (Bob) McArdle married Barbara Carter at Broken Hill. They had two children, Kathleen Wattle McArdle and Robert Maurice McArdle. Robert did not survive one year and was buried in Broken Hill in September 1916. Vic may have left Broken Hill to work on the Railways in South Australia some time after 1917. The last time Vic appears on the electoral roll in Broken Hill is 1917 and the last time Maurice (Bob) and Barbara appear on the electoral roll for Broken Hill is 1919. Little is known of what happened to the family for the next twenty years.

By 1939, Maurice (Bob) McArdle shows up in Adelaide as a farrier living at 314 Halifax Street. By 1941 he has remarried to Agnes Lucy Willis. Bob lives at 314 Halifax Street until his death in 1954. He met a tragic end as reported in the "Adelaide Advertiser" on the front page of the February 8th issue "Man Found Dead In City Fire". Maurice was buried in the Catholic Cemtery, West Terrace, Adelaide.
