The Capricornian (Rockhampton, Qld) - Saturday 7 June 1890 - Notes of the Week...
"The most important case heard at the Police Court this week occupied the Police Magistrate yesterday morning, when Gibson Stewart, alias George Stewart, a working man of respectable appearance, was charged with bigamy. The case was gone into exhaustively, and the evidence showed that on the 12th of January, 1887, the prisoner was married to Miss Laura Jane Jones, at the residence of his father in Ipswich, by the Rev. Mr. Walker, Congregational Minister. He lived with his wife until Christmas, 1888, when he came to Rockhampton, met a young woman named Margaret Spellman, became engaged to her, and subsequently was married to her by the Rev. Father M'Donough, in the Roman Catholic Presbytery, on the 30th of September, 1889. Both the women with whom the prisoner had undergone the marriage ceremony were present in Court. Both are young and goodlooking. They fraternised more cordially than could have been expected under the circumstances. The prisoner, who has announced his intention of pleading guilty, has been remanded."

The Capricornian (Rockhampton, Qld) - Saturday 14 June 1890 - Notes of the week
"George Stewart, alias Gibson Stewart, has pleaded guilty to the charge of bigamy, and will come up for sentence at the sitting of the Central District Court on Monday."

Morning Bulletin (Rockhampton, Qld) - Tuesday 17 June 1890 - Central District court
"BIGAMY
Gibson Stewart, alias George Stewart, was charged with bigamy, in having gone through the marriage ceremony with Margaret Spellman, at Rockhampton, on the 21st September, 1889, while his lawful wife Laura Jane Gibson was still alive. The prisoner had pleaded guilty at the Police Court proceedings, and was now brought up for sentence. The facts of the case will be fresh in the minds of the public, as the prisoner was only committed for sentence at the Police Court on the 7th instant. Prisoner said he had nothing to say, and no witnesses to call.
His Honour said the offence of bigamy was a very serious one, and there was no doubt the prisoner had cruelly wronged an innocent girl. The law meted out very severe punishment for the crime, and nothing that he could see in the depositions offered the slightest excuse for prisoner's conduct. The sentence of the Court was that accused be imprisoned and kept to hard labour in Brisbane gaol for two years."
