Jerry and his brother, Paper Talk, were born in the Eudamullah area. Jerry was a faithful servant and workman to Guy Viveash on Jimba Jimba Station. Their father was head man of their Aboriginal tribe and Jerry was to be his successor. As Jerry grew older, he would gravitate between the place of his birth and Jimba Jimba. One day, Jerry received word that his brother had passed away and had been given the proper burial, with the necessary wailing and ceremony. Knowing his time was short, Jerry and his skinny old dog were on the next mail truck back to Eudamullah, as he wanted his own people to arrange his burial.

Known as Jack.

Police headquarters announced that information had been received that Jack Kilgallon, a station hand, was found dead in bed at Eudamullah Station which is situated about sixty miles south east of Gascoyne Junction. Death, it was stated, was due to heart failure, and the Coroner, after having been notified, decided not to hold an inquest.

Kilgallon's parents came from Ireland and were married in Sligo, Ireland, in 1860 after Mchaelis Kilgallon had served 21 years 13 days in the military and was discharged in 13 September 1859.

John's wife, Esther Ellen Grady, died 15 March 1915 at Northam (Death Registration 4900025/1915, Northam).
