Lieutenant General Henry Wray CMG, 1826-1900, arrived in Fremantle 18 December 1851 with other married soldiers of 20th Company, Royal Engineers. He was born in Demerara, and died in Bournemouth. He arrived on the Anna Robertson, and left on the Nile in February 1858.
He supervised the construction of the Convict Establishment/Depot (Fremantle Prison) following Edmund Henderson's designs. He designed many other public works in the Colony; and was also a magistrate. After Henderson left, he was acting Comptroller General of Convicts 1856-8, after which he left Australia.

In 1854, Wray persuaded Governor FitzGerald to order from England an 'apparatus' for the conversion of xanthorrhoea to gas for the lighting of the Convict Establishment (the prison). While waiting, he carried out experiments which showed that gas could be extracted from the plant and burnt with a useful flame. However, the apparatus did not arrive until October 1858, and Wray had left by that time. The next Governor, Kennedy, was not so keen on the idea, despite support for it from Henderson, and the apparatus was never used.
After leaving the Colony, Wray re-entered the service, in Malta and Ireland, and was promoted to Major General in 1882. He ended his career as Governor of Jersey, and retired in 1887 with the rank of Lieutenant General. He died of pneumonia in April 1900.
Two of his children have memorials in Fremantle, in the first (Alma St) cemetery: Alice, who died at sea in 1851; and Henry, in 1855. Their tombstones are preserved in the Alma St Heritage Garden. The Wrays left England on the Anna Robertson in September, Alice died in October, and they didn't arrive until December, so I assume her body would have been committed to the sea, and that the stone is not the headstone from her grave, but rather a memorial.
